1. Scope of Policy
Keele University recognises its responsibility to ensure that all employees and those
contractors and suppliers engaged by Keele University, directly or via third parties, to work
on its sites and premises comply with all relevant statutory requirements for the safe
management, isolation and re-energisation of electrical systems owned and managed by the
University.
The University accepts its responsibility to take every reasonable precaution as outlined in
The Electricity at Work Regulations 1989 to protect occupiers, users, contractors and visitors
within the vicinity of the campus.
Electricity can prove fatal, or can cause serious injury and burns, as confirmed by vast
numbers of cases, all of which could have been prevented. It is these preventative
measures that Keele University wishes to address across its portfolio for the protection of
students, staff, contractors and visitors. The associated liability of such a fatality or injury,
necessitates the need for clear, concise guidelines to be published, recommending
measures to be taken to prevent injury or fatality within the buildings owned, managed or
maintained by Keele University.
Electrical services, in particular switch rooms, are the areas requiring close scrutiny
regarding maintenance methods and procedures.
The measures to be taken for our management of this risk are contained within this
document.

2. Policy Statement
The University recognises and accepts its responsibility as an employer for providing, as far
as reasonably practicable, a safe and healthy working environment for its employees. In
addition, it will ensure, so far as is reasonably practicable, that persons other than
employees, including students, visitors and contractors, are not exposed to risks to their
health and safety.
The University also requires employees to take reasonable care of their own health and
safety, and that of other persons who may be affected by their acts or omissions at work.
Employees are also required to co-operate with the University and any other person to
enable them to meet their own statutory obligations.
These rules are assembled to establish safe working practices for the protection of those
whose specific role involves work on low voltage (exceeding extra-low voltage but not
exceeding 1000V a.c. or 1500V d.c. between conductors, or 600v a.c. or 900V d.c. between
conductors and Earth) electrical systems and equipment on Keele University sites and
premises.
The rules govern work associated with Keele University electrical systems and equipment,
and apply to both Keele University employees and those contractors and suppliers engaged
by Keele University, directly or via third parties, to work on its sites and premises.
Note: Any work undertaken may also be governed by Keele University policies and safety
rules other than those for electrical safety, such as those applying to general occupational
health and safety matters and not least the requirement that work activities are subjected
to risk assessment and safe system of work / method statement.
7
3. Legislation and Guidance

vi) Appoint a person to be managerially responsible.
3.2 Statutory and Dedicated Legislation Applying to Electrical Systems
a. Health and Safety at Work etc. Act 1974
The management have a duty to ensure that there is an appropriate regime for the
design, installation and maintenance of electrical plant and systems. A proper
system of work and adequate control measures are essential to conform with this
Act.
b. Management of Health and Safety at Work Regulations 1999
These Regulations provide a broad framework for controlling health and safety at
work. To comply with them the management must make a suitable and sufficient
8
assessment of risks to health and safety for its employees and others arising from
work activities.
c. The Electricity at Work Regulations 1989
The Electricity at Work Regulations 1989 (as amended) came into force on 1 April
1990. The purpose of the Regulations is to require precautions to be taken against
the risk of death or personal injury from electricity in work activities.
d. The Electricity Safety, Quality and Continuity Regulations 2002
The new Regulations specify safety standards which are aimed at protecting the
general public and consumers from danger. In addition, the Regulations specify
power quality and supply continuity requirements to ensure an efficient and
economic electricity supply service for consumers.
e. The Control of Asbestos Regulations 2012
The Control of Asbestos Regulations 2012 (the Regulations) set minimum standards
for the protection of employees from risks related to exposure to asbestos.
Employers should also take account of people not directly employed by them but
who could be affected by the work being done on asbestos (including employees of
other employers, people occupying buildings, members of the public etc.).
In addition the following procedure documents and guidance should be referred to for
information.
• BS7671:2008 (As Amended) Requirements for Electrical Installations. IET Wiring
Regulations Seventeenth Edition
• IET Guidance Notes 1-8
• Electrical Safety Council, Best Practice Guide 2 Issue 3 (Or latest issue)
• HSE Publication GS38
• The EEC Standards and Directives
• The British Standards Guidance Notes
• Other HSE Guidance Notes

4. Rationale for Policy
Electricity has many uses, the most common of which are light, power, heating (air and
water) and ventilation. However electricity is extremely dangerous.
Electrical danger is the risk of injury to persons from fire, electric shock, burns, arcing and
explosion from the use of electrical energy.
The lethality of an electric shock is dependent on several variables:
Current - The higher the current, the more likely it is lethal. Since current is proportional to
voltage when resistance is fixed (Ohm's law), high voltage is an indirect risk for producing
higher currents.
Duration - The longer the duration, the more likely it is lethal
Pathway - If current flows through the heart muscle, it is more likely to be lethal.
Voltage - In addition to greater current flow, higher voltages may cause dielectric
breakdown at the skin, thus lowering skin resistance and allowing further increased current
flow.
All of the above factors can be mitigated with a robust, concise electrical safety policy and
suitable training to all staff and contractors on the content of such policy.
10
5. Management

regulation that affects the way in which electrical isolation is carried out.
14
6. Isolation Procedures
6.1 Pre-work Inspection and checks.
Before any work commences, it is imperative that all RAMS are submitted to the university
and that all persons are checked as being a skilled person (electrically). A list should be kept
and updated by the University of persons assessed as skilled, registered to work on the
university systems.
A check must be made with the RP that the correct point of isolation is being used.
All test instruments should be checked to ensure that they are compliant with the
requirements of GS38.
Ensure that the following information is obtained and understood
• The nature and extent of the work to be done
• The area in which it is safe to work
• Their own responsibilities for safety
• The safety precautions in force
• The asbestos information for the Site / Area
6.2 Use of these Isolation Procedures
The electrical contractor is allowed under this policy to carry out their own isolations,
subject to competency of staff, RAMS detailing a suitable isolation procedure. These
isolation procedures below come into effect if the contractor is unable to supply a set of
approved RAMS detailing their own LV isolation procedures.
6.3 Objection to Instructions
If a person has an objection on safety grounds to instructions received for work on, or the
operation of, electrical plant, he shall make his objection known to his line manager. The
manager shall consider the matter immediately, referring to the PEE if the matter cannot be
otherwise resolved.
6.4 Access to LV Switchroom
Only persons who are classified as Skilled Person (electrically) or persons who are in their
direct supervision are allowed to enter university LV switchrooms.
15
6.5 Access to HV / LV Shared Switchroom
Only persons who have passed the HV Senior Appointed Persons (HVSAP), HV Appointed
Persons (HVAP) course, HV Sub-station access course or are under direct supervision from
any of the above, may enter the University HV Switchrooms or sub-stations.
6.6 Lock out Kits, Proving Units, Test Lamps and Danger Notices
In order to carry out the safe isolation of an installation or part thereof it will be necessary
to use a voltage indicating device. HSE state clearly in guidance note GS 38 - Electrical test
equipment for use by electricians that contact type voltage detectors and test lamps
specifically designed to identify whether or not a voltage is present should be used for this
purpose.
The use of multi-range instruments is not recommended as it is possible to select an
inappropriate range setting; the leads may not be sufficiently robust; and the probes may
have excessive bare metal exposed; all of which may possibly put the user in danger.
Reliance on non-contact type voltage indicators is also not recommended for use as the sole
means of confirming that a circuit or piece of equipment has been made dead.
A wide range of contact type voltage indicating device are available. The general condition
of a voltage indicator should be checked prior to each use and especially if the instrument
has not been used for some time. Particular attention should be paid to the outer casing,
leads, and probes. Only the minimum amount of probe should be exposed to allow the
instrument to be used correctly.
If a voltage indicator shows significant damage or deterioration, the voltage indicating
device, or where appropriate, the component parts in question, such as tips and lamps,
should be replaced before further use.
The functionality of a voltage indicating device must be confirmed prior to each use. This
can be achieved by checking on a known supply or perhaps more conveniently by using a
proving unit.
6.7 Request To Isolate
A request to isolate form must be filled in by the engineer and issued to the RP prior to any
works commencing. See Appendix 4.
6.8 Sub Permit To Work
A sub-permit to work must be filled in by the RP or deputy RP referencing the request to
isolate prior to issuing a permit to work. See Appendix 5.
16
6.9 Permit To Work
Once all the pre-work inspection and checks have been completed and a request to isolate
has been received by the RP and a sub permit to work issued, the electrical system to be
worked on must be isolated by the RP and a permit to work issued. The ‘LV Safe Isolation
Procedure’ (Appendix 3) must be followed. A multi hasp lock must be used to lock off the
equipment isolated with one padlock from the RP and the other padlock from the engineer.
Each key must be kept with the respective person at all times. See Appendix 6.
6.10 Cancellation of Permit and Re-Energisation of Supplies
Once all works to the electrical system have been completed, the RP must re-energise the
supply and cancel the permit to work and sub-permit to work. No supply is to be re-
energised until inspection and testing and certification has been carried out in accordance
with Part 6 of BS7671 (As amended).
Before reconnection of the supply, as much downstream load as is reasonably practicable
must be isolated as possible to reduce arcing or the possibility of flashover.
6.11 Isolation by Other E&D Trades
The E&D plumbing and heating staff have received safe isolation training to allow them to
isolate boilers and pumps to allow removal/repair.
17
7. Live Working Procedures
IMPORTANT No work of any kind is to be carried out on LV equipment when the equipment
is live if the purpose of the work can be achieved with the power isolated.
7.1 Pre-work Inspection and checks.
Before any work commences, it is imperative that all RAMS are submitted to the university
and that all persons are checked as being a skilled person (electrically). A list should be kept
and updated by the University of persons assessed as skilled, registered to work on the
university systems.
Ensure that the following information is obtained and understood
• The nature and extent of the work to be done
• The area in which it is safe to work
• Their own responsibilities for safety
• The safety precautions in force
• The asbestos information for the Site / Area
7.2 Objection to Instructions
If a person has an objection on safety grounds to instructions received for work on, or the
operation of, electrical plant, he shall make his objection known to his line manager. The
manager shall consider the matter immediately, referring to the PEE if the matter cannot be
otherwise resolved.
7.3 Live Working Notes
No work of any kind is to be carried out on LV equipment when the equipment is live if the
purpose of the work can be achieved with the power isolated.
If it is not possible to complete the work without de-energising the equipment, this will only
be permitted if an LVAP has issued a PTW which will identify all risks and all measures to be
taken to minimise the potential danger.
18
7.4 Live Testing
Apart from Inspection and testing as defined in Part 6 of BS7671 (As Amended), live testing
is permitted only in the following circumstances:
• The use of approved equipment for the purpose of voltage detection on a live circuit,
but only where it is a necessary part of the test involved. In such circumstances the
test equipment used should comply with HSE Guidance Note GS38 – Electrical Test
Equipment for use by Electricians, and adequate precautions are to be taken to avoid
access to the equipment under test by persons not involved with the testing.
• Any test or inspection procedure, other than voltage detection on a live circuit,
which is necessary to be undertaken live. The test or procedure is to be specifically
authorised by an LVAP. The LVAP authorising such live testing must attend and
remain present for the duration of the operation. In no circumstances may an LVAP
authorise himself to do such tests.
7.5 Electricity at Work Regulations 1989
The LVRP / LVDRP shall not authorise live testing or inspection procedures unless he is
satisfied that the requirements of Regulation 14 of the Electricity at Work Regulations are
satisfied:
No person shall be engaged in any work activity on or so near any live conductor (other than
one suitably covered with insulating material so as to prevent danger) that danger may arise
unless –
• It is unreasonable in all the circumstances for it to be dead; and
• It is reasonable in all the circumstances for him to be at work on or near it while it is
live; and
• Suitable precautions (including where necessary the provision of suitable protective
equipment) are taken to prevent injury.
7.6 Limitation of Live Testing Part 6 of BS7671 (As Amended)
It is university policy that live testing is not carried out to the furthest point of any circuit to
establish a Zs reading. A calculated value should be inserted using the measured r1+r2
reading for the circuit added to Zdb.
The formula for the value to be inserted in the Zs value box is: Zs = Zdb + (r1 + r2)
19
Appendix 1 – Emergency Procedure
Loss of Supply
On experiencing a complete or partial electrical power loss inform estates helpdesk (01782 733134),
security (01782 733004), the RP (Ash Hulme, 01782 733135) and the DRP (Chris Beeston, 01782
734544).
Await confirmation from the ‘on site’ electrician of the extent of the problem.
On instruction from the RP or DRP, security shall evacuate the affected building(s) if necessary.
If the power loss is localised, E&D security team are authorised to attempt to reset MCB’s or RCBO’s
up to and including 32A Single Phase. If this is not successful, the E&D electrical engineers must be
informed.
Electric Shock
It may not be immediately clear, but if you think someone is suffering from electric shock, approach
with extreme caution.
The first step is to separate the person from the source of electricity as quickly as possible. The best
way of doing this is to turn off the supply, for example, by unplugging the appliance or by turning the
supply off
If this isn’t possible, then try to remove the source of electricity from the person using a piece of
insulating material, such as a length of wood.
NEVER touch the person receiving the electric shock, or you could suffer one too.
After removing the person from the source of electricity, if the person is unconscious call for an
ambulance immediately. Only those with the necessary knowledge and skill should carry out first
aid.
Where the person is conscious and seems well, it is still advisable to monitor their condition, as the
effects of an electric shock may not be immediately obvious. In worst case conditions, an electric
shock may lead to a condition known as electroporation, where cells within the body rupture,
leading to tissue death. Additional problems might include deep-seated burns, muscle damage and
broken bones.
20
Appendix 2 – Emergency Aid
1) Danger If you suspect someone has received an electric shock you must ensure all power sources are isolated before you can treat the casualty.
• High Voltage High voltage electricity has the ability to ‘jump’ or ‘arc’ up to distances of 18 metres or over. If faced with a casualty resulting from high voltage electricity: Do not approach! Stay at least 25 metres away from the casualty until the power has been switched off by an official agency i.e. Electricity Board / Estates Department.
• Low voltage If faced with a casualty who is in the process of receiving an electric shock you should: - Attempt to turn the power off at the mains. - Remove any cables/power tools etc., still in contact with the casualty.
• Action to take - Insulate yourself from the ground with books / newspapers / rubber matting - Use an object of low conductivity i.e. a wooden broom or rolled up newspaper to push away the power source.
2) Response To give your casualty the optimum chance of survival you must quickly assess their levels of response. A rapid assessment will allow effective treatment to be administered and will also allow for accurate information to be passed on to the ambulance service.
• Check whether the casualty is conscious 1. Ask “hello, can you hear me” and call their name if you know it. 2. Ask in both the casualty’s ears to open their eyes. 3. Pinch an ear lobe or gently tap the shoulders. 4. Shout for HELP! 5. DO NOT move the casualty unless the environment or situation is dangerous.
21
3) Danger
• Call for help If alone call for help. If someone responds to your call ask them to stay with you whilst you assess the Airway and Breathing. One of you should wait with the casualty whilst the other calls an ambulance. NB: If no-one responds do not leave the casualty but go on to assess the airway and breathing.
• Calling the emergency medical services: 1. Lift the receiver and wait for a dialling tone. 2. Dial 999 in UK (112 in Europe) 3. The operator will ask you which service you require. Once you have stated ‘ambulance’ you will be connected to ambulance control. The operator will ask you a set of questions. DO NOT hang up at any stage of the conversation. The operator will terminate the call when appropriate. Inform KU Security (888) as they will direct the ambulance to the correct location. Isolate or cordon off the exposed, damaged or faulty electrical source if safe to do so. As soon as possible, after the casualty has been taken to hospital report the incident to the local supervisor. Give all information you can as an IRF needs to be completed for all accidents and incidents. Leave details about yourself so that you can be contacted should the need arise. Report defective equipment that caused the shock (if applicable), so that repairs can be made. RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995) 4) Airway and Breathing
• For an unresponsive casualty open the airway
1. Look in the mouth to ensure there are no obvious obstructions. 2. Open the airway by lifting the chin and tilting the head back. This will free the
22
tongue from the back of the throat. 3. If neck/spinal injury is suspected, put one hand on the stomach to feel if it rises and falls. This indicates normal breathing.
• Assess for breathing 1. LOOK for the rise and fall of the chest. 2. LISTEN for sounds of breathing. 3. FEEL for air on your cheek. 4. Carry this out for up to 10 seconds.
• Breathing normally If breathing is present go straight to the Recovery Position section.
• Not breathing If the casualty is not breathing normally, commence full Cardio-Pulmonary Resuscitation (CPR). If you are alone, leave the casualty at this stage and call for help. Return to the casualty and commence CPR (Cardio-Pulmonary Resuscitation). 5) Unconscious – Not Breathing To commence CPR:
• For an unresponsive casualty 1. Ensure the casualty is on a firm, flat surface 2. Place your hands one on top of the other in the centre of the casualty’s chest 3. Compress the chest (up to a maximum depth of approximately 4-5cm) 30 times at a rate of 100 compressions per minute. The compressions and releases should take an equal amount of time 4. After 30 compressions, open the airway again using head tilt/chin lift 5. Seal the nostrils with your thumb and forefinger. 6. Blow steadily into the mouth until you see the chest rise, take about a second to make the chest rise. It is advisable to have Resuscitation Equipment at this stage such as a face shield. 7. Remove your mouth to the side and let chest fall. Inhale some fresh air, when breathing for the casualty 8. Repeat so you have given 2 effective rescue breaths in total 9. If chest does not rise after the second breath, go back to 30 compressions then try again with 2 breaths. 10. Return your hands to the correct position on the chest and give a further 30 chest compressions.
• Continue with CPR until: - The casualty shows signs of recovery - Emergency services arrive - You become exhausted and unable to continue - The situation changes and you are now in immediate danger. 6) Defibrillation Use an AED (Automatic External Defibrillator) if available and follow prompts. 7) Recovery Position If the casualty is unconscious and breathing normally, turn the casualty into the recovery position. - The recovery position is used when a casualty is unconscious and breathing. - The recovery position allows the head to be placed tilted back and down. This stops
23
the tongue from blocking the airway and will allow any vomit and fluid to drain from the mouth.
• If the casualty is breathing normally • 1. Check for any other obvious injuries.
2. Remove sharp objects from pockets. 3. Turn the casualty into the recovery position. 4. Place the nearest arm at a right angle to the body. 5. Draw the furthest arm across the chest and place the back of the hand across the cheek. 6. Keep this here whilst you raise the furthest leg by grasping the top of the knee. 7. Gently pull on the knee so that the casualty pivots over onto their side facing you. 8. The casualty should be fully over and stable. 9. Re-check the airway, breathing and circulation. 10. Draw up the leg at a 90 degree angle. 11. Check for continued breathing. 12. Call the emergency medical services:
1. Lift the receiver and wait for a dialling tone. 2. Dial 999 in UK (112 in Europe) 3. The operator will ask you which service you require. Once you have stated ‘ambulance’ you will be connected to ambulance control. The operator will ask you a set of questions. DO NOT hang up at any stage of the conversation. The operator will terminate the call when appropriate. 4. Inform KU Security (888) as they will direct the ambulance to the correct location
8) Burns Exposure to electricity can cause burns to the skin and, in severe cases, internal organs. In such cases the electricity may, for example, enter via a hand and leave via the feet causing ‘entry’ and ‘exit’ burns.
• Conscious casualties Cool burns for a minimum of 10 minutes under cold water.
• Unconscious casualties Cool the burn with wet dressings after placing them in the recovery position.
• DO NOT - Burst any blisters - Apply adhesive dressings - Remove damaged skin - Apply ointments/creams - Cover with ‘fluffy’ dressings - Affix dressing too tightly - Apply butter/fats/margarine
24
- Remove damaged clothing - Apply ice. 9) Other Injuries
• Muscle spasm/seizures These may be present for some time after the exposure to electricity and indicate a seriously ill casualty.
• Action in the event of a major seizure 1. The casualty will almost definitely collapse during a major seizure. Try to control the fall. 2. Ensure the safety of the casualty by removing any objects that may cause injury if they are struck. 3. Place padding under the head of the casualty. Improvise if necessary by using clothing. 4. DO NOT place anything in the casualty’s mouth. 5. Loosen any clothing that may restrict the airway. 6. When the seizure has subsided: 7. Check the casualty’s Airway, Breathing and Circulation (ABC). 8. If unconscious and breathing normally or semi-conscious, place the casualty in the recovery position (see above). Perform CPR if not breathing. 9. Can also put a blanket over casualty to preserve modesty, also time the seizure. 10. Reassure the casualty whilst continuing to monitor the ABC and any other injuries.
• Casualties with no apparent injury: If no injury is present and the casualty appears well, it is still advisable to take the casualty to a hospital or medical facility for a check up, as certain organs/systems within the body may be affected several hours after a shock.

Appendix 13 – Temporary Connections to Keele Network
Introduction
The following appendix provides guidance on the safe use of electrical appliances and
means of providing electricity to such within the external areas of the campus and within
university buildings.
This appendix, and any / all others associated with the event MUST be adhered to. Failure to
do so may result in the event being terminated due to safety concerns.
Throughout the year, several indoor and outdoor events are held at Keele University. These
events inadvertently involve some element of electrical connection to the Keele network.
These are usually appliances and/or extension leads plugged into one of many feeder pillars
installed around the campus for the purpose of temporary events or small scale generators
to supply individual items of equipment.
Keele University recognises that some installations are exposed to many differing and
onerous circumstances, as they are often frequently installed, dismantled, moved to a new
location then installed and operated again.
To compound the problem, such installations are frequently exposed to the elements and
are frequented by the general public, staff, students and children. There is also a risk, as this
is an open campus, of unauthorised access.
The equipment must function without compromising safety. The installation has to,
therefore, be fit for purpose and designed to cope with ever changing conditions.
The fact that an installation is temporary should mean that the installation standards are
any less than that of a fixed installation. Indeed, due to the conditions listed above, the
installation frequently has to be of a higher standard than that of a fixed installation.
Section 711 and Section 740 (BS 7671:2008 + A3:2015) are particularly relevant to these
types of installations. The requirements of these sections must be given special
consideration but must be read alongside the other requirements of BS7671:2008 (As
Amended).
Process of application for connection of appliances for events
General
The use of electrical appliances for events shall be subject to approval by Keele University
Estates & Development Directorate (Keele University E&D Directorate). The following
process shall be followed:-
Step 1 – Identify preferred location of the event / area requiring electricity.
43
Step 2 – Produce a plan showing location and size of all parts of the event. Plans can be
obtained from the Keele University E&D Directorate team. All fixed structures (Marquees /
tents etc) and large free standing equipment (tables etc) should be identified on the plan.
Step 3 – Identify a list of electrical appliances to be used, and their ratings.
The list should include all lighting within Marquees, DJ equipment, catering equipment.
The rating will be stamped on the equipment. The voltage (230V or 400V) and power rating
(Watts / W / kW) need to be provided.
Portable Appliance Test certificates for all equipment to be connected must be provided.
Step 4 – Determine a method of electrical distribution i.e. 230V 13A extension leads or a
‘commando’ temporary distribution unit system.
Where a large marquee is being provided by an external company it will generally be
a ‘commando’ temporary distribution system. These will generally need to be provided and
installed by the Marquee company.
Where events are within a building, generally 230V 13A extension leads will be used.
Extension leads can be obtained and installed by Keele University E&D Directorate (this is
generally a chargeable service).
Step 5 – Note any nearby electrical connection points and make note of the reference. This
is only relevant for external events.
Step 6 – Provide the above information / request to Keele University E&D Directorate a
minimum of 4 weeks prior to event date.
Step 7 – Final scheme to be agreed with Keele University E&D Directorate.
Step 8 – Keele University E&D Directorate to carry out pre-use electrical tests of the
connection points and carry out final connection to KU infrastructure.
Step 9 – Any electrical issues during the event during normal working hours are to be
reported to Keele University E&D Directorate Helpdesk, any issues out of normal working
hours are to be reported to KU Security.
Any electrical issues affecting KU infrastructure shall only repaired by Keele University E&D
Directorate operatives. Tampering by the event organisers / operators shall not be
permitted.
Any electrical issues caused by equipment within the event must be disconnected and
removed from service; until this is done re-energisation of supplies will not be permitted.
44
Pre-use tests of external electrical connection points
Keele University E&D Directorate shall undertake the following tests on the day prior to the
event and carry out any repairs required:
- Functional and mechanical test of all RCD’s / RCBO’s.
- Earth fault loop impedance test at the main isolator.
- Visual inspection.
Pre-use tests of internal electrical connection points
Keele University E&D Directorate shall undertake the following tests on the day prior to the
event and carry out any repairs required:
- Functional test of all RCD’s / RCBO’s.
- Visual inspection.
Location of external electrical connection points
General
The external electrical connection point shall be discussed with Keele University E&D
Directorate to determine the most suitable area of supply.
Connections to Feeder Pillars
All connections to feeder pillars must be carried out by E&D electrical staff. No supplies are
to be energised until Portable Appliance Testing (PAT) certificates have been verified for all
items of equipment to be connected to the Keele network.
It is imperative that all items of equipment are of a suitable IP and IK rating for the
installation method and installation location.
Any trailing leads from feeder pillars must be routed in such a way to avoid, so far as is
reasonably practicable, crossing walkways or roads. Where this is unavoidable, the cables
must be suitably secured and protected to prevent damage to the cables and avoid any trip
hazards.
Security of Feeder Pillars
All external electrical connection points shall be locked via use of an KU Electrical ASSA suite
lock.
All new external connection points shall be provided with a ‘cat flap’ for connection of
trailing
45
leads, the ‘cat flap’ shall include a weatherproof seal and be secured by means of a hasp and
staple and an KU Electrical ASSA suited padlock.
Keys shall be retained by Keele University E&D Directorate. Keys shall not be issued to the
Event organisers / operators.
Electricity Consumption
Electricity will generally be provided free of charge, however dependant on the type of
event and anticipated consumption, there may be a charge.
Use of Generators on Campus
General
Generators are strictly forbidden on campus, except without express permission of Keele
University E&D Directorate.
Generators shall not be permitted within a building.
Generators shall only be considered for external events where there is not a local electrical
power supply, and the event cannot reasonably be located near to a local electrical power
supply.
Process for application of use of a generator
The following process shall be followed:
Step 1 – Identify preferred location of the generator and produce a plan.
The generator should be located in a position easily accessible by the delivery company.
The generator should be positioned such that the noise, heat and fumes do not cause
disruption to the general activities of the University.
Plans can be obtained from the Keele University E&D Directorate team.
Step 2 – Identify the generator electrical size.
Identify a list of electrical appliances to be used, their ratings and anticipated operational
time. This list will enable the supply company to suitably size the generator and any external
fuel tanks as needed.
Step 3 – Identify re-fuelling / fuel storage / supply requirements.
46
The use of plastic fuel cans shall not be permitted onsite. Where a petrol generator up to
4kVA used metal fuel cans securely stored may be used to re-fill the generator. Re-filling
must be carried out with the generator OFF and COLD.
Where generators above 4kVA are used onsite and additional fuel is envisaged a static
plumbed in fuel tank must be provided.
Fuel must be securely stored and away from naked flames/ heat.
Step 4 – Determine a method of electrical distribution i.e. 230V 13A extension leads or a
‘commando’ temporary distribution unit system.
Where a large marquee is being provided by an external company it will generally be a
‘commando’ temporary distribution system. These will generally need to be provided and
installed by the marquee company.
Step 5 – Provide the above information / request to Keele University E&D Directorate a
minimum of 4 weeks prior to event date.
Step 6 – Final scheme to be agreed with Keele University E&D Directorate.
Step 7 – A copy of the generator test certificates are to be provided to Keele University E&D
Directorate prior to the start of the event.
Step 8 – Any electrical issues during the event are to be rectified by the generator hire
company. Keele University E&D Directorate can provide assistance if required, however will
be chargeable.

Use of Internal Power Supplies / Outlets For Events
General
Where rooms within University buildings are used for events, the event organiser must
follow the procedure earlier in this appendix. This is to ensure that Keele University E&D
Directorate have the opportunity to review the appliances to be connected and the
available electrical infrastructure to ensure that the infrastructure is not unintentionally
overloaded.
Where extension leads are required these can be provided and connected by Keele
University E&D Directorate department. This is a chargeable service.
Electricity will generally be provided free of charge, however dependant on the type of
event and anticipated consumption, there may be a charge.

Appendix 16 – Agreed Limitations on Inspection and Testing
Inspection and testing must be carried out on all circuits following modification, installation or repair. In accordance with BS7671 Part 6 and IET Guidance Note 3. Agreed limitations Minor Works Where a minor works certificate is required, N-E insulation resistance testing may be recorded as an agreed limitation. The circuit should be isolated and locked off at the distribution board or consumer unit and insulation resistance tested at the furthest point of the circuit or the added point between L-N and L-E. These values should be recorded on the certificate as prescribed. Please note for Keele directly employed staff or artisan staff, clause 7.6 of this document does not apply to obtaining Zs readings for minor works certification. These should be obtained by live testing. Agreed Limitations Periodic Inspection and Testing. Insulation resistance testing between neutral and earth may be recorded as an agreed limitation on lighting circuits. No live testing to be carried out in accordance with clause 7.6 of this document. Zs is to be obtained by calculation utilising the formula Zs=Zdb + (r1 + r2). Standard agreed limitations as prescribed in part D of the Electrical Installation Condition Report also apply. Changing Accessories only.
The following paragraph only applies to Keele direct labour and artisan staff.
Where an accessory is changed on a like for like basis, there will be no need to complete a minor works
certificate in full. A Zs reading should be obtained prior to replacement (if safe to energise accessory) and a
Zs reading measured after replacement. These readings should be substantially the same (<=0.05 ohm
different). If a difference is measured greater than this limit, the circuit should be further investigated. The
before and after readings must be recorded on the Q5 job ticket.
Test Certification.
On the electrical certification, the following wording should be inserted into the agreed limitation box.
“Agreed limitations as per Appendix 16 of Keele University Electrical Safety Management Policy Low
Voltage”
In the as agreed with box, the name “A. Hulme” is to be inserted
Limitations agreed:
