Tonight we will cover:

the variations between the 2005 and the 2014 versions of the Service and Installation Rules.

go over certain selected areas within the new SIRs

remove confusion and Highlight areas where major non-compliance often occurs.

Service and Installation Rules NECAJanuary - February - March 2014

Welcome

33

Where do the Service and Installation Rules (SIR) fit in?

Under the Sale and Distribution Code, Known as the Distributors reasonable technical requirements.

Traditionally cover off supply connection methods, metering and supply arrangements.


SIR Fit

44


Compliance

Do I need to comply with the SIRs are they mandatory?

Yes you shall comply;

If you do not comply then FIP (fuse in pocket) usually applies. No Supply.

For safe connection and metering of electrical installations you are required to comply with the Sale and Distribution Code.

Remember any delays will effect your customer.

55


Application

The Victorian Service & Installation Rules apply to all connections to the electricity supply networks operated by Electricity Distributors: CitiPower, Jemena Electricity Network, Powercor Australia Ltd, SP AusNet and United Energy.

The objective of these Rules is to: provide Victorian electricity customers with industry agreed reasonable

technical requirements that; meet all legislative and Electricity Distribution Code requirements

for the supply and metering related aspects of any connection to the Victorian Distributors electricity supply networks.

66


Public Notice - Availability of the 2014 Service and Installation RulesThe 2014 SIR are applicable from 1st January 2014 with a three month period of transition allowing the trade to adopt and employ the changes in the new document. There may be exceptional circumstances, if a connection post 31st March 2014 exists where a REC wishes to have the 2005 rules applied an SIR exemptions must be submitted by a written request detailing the reasons why non-compliance with the 2014 Rules is sought.

An exception to the 2005 Rules will not be automatically granted, electrical work associated with the exception should be discontinued until approval from the Distributor is received.

A host of additional standards are also applicable to components and sub systemsincluding rotation machines, earthing, switchgear and fuses, transformers, cabling,labelling etc. Alternative supplies that are also embedded generators must comply withCodes made under the National Electricity Rules and specific Generator ConnectionStandards issued by each Distributor.

2020


Changes - Section Six (6) Alternative Supplies.Generally all alternative supplies shall:

* Be arranged to disconnect from and not back energise the Distributor'snetwork and service and metering equipment if electricity supply from thenetwork is de-energised (unless explicitly allowed by the Distributor).

* Have electrical characteristics compatible with the relevant Distributor'snetwork

* Not interfere with supply quality to other customers or the Distributor'snetwork.

Changes - Section Six (6).

Supply Protection requirements

The Electricity Safety Act requires service lines to be protected by protective equipment that can isolate each of the active conductors of an electrical installation and prescribes their location.

For Overhead supplies Network Overhead

Underground URD supplies Network Underground

Supplied direct from a sub-station sub-stations

2424


Changes - Section Six (6). Supply Protection Devices (SPD).

Main Principle to be achieved.

The customer shall install and maintain an assembly to accommodate supply protection device/s (SPD) in accordance with the Electricity Safety (Installations) Regulations, these Rules and the obligations of the Distributor to connect and disconnect electrical installations.

17/04/2014

2525



A Supply Protection Device shall Minimise any adverse conditions which may affect other customers

electrical installations and the distribution system. The SPD must ensure adequate protection is provided up to the electrical protective equipment of the electrical installations they supply.

Note: In some cases Distributors may utilise their HV protection equipment for supply protection. It will be necessary to confirm the supply protection arrangement with the relevant distributor at the design stage of the electrical installation.

Also Enable the Distributor to connect, disconnect and isolate each active

conductor supplying the electrical installation for commercial and/or safety reasons; and not exceed one device per phase

2626



Assemblies to accommodate LV Supply Protection Devices (SPD)

The customer is responsible for the provision of an assembly to accommodate Supply Protective Device/s (SPD) provided by the Distributor. This equipment must be of an acceptable type as required by these Rules and shall be located and installed in accordance with the relevant requirements of the current Electricity Safety Act and Regulations.

Access

The assembly for the purpose of accommodating the SPD shall be installed in a position where convenient and unhindered access is readily available for the Distributor to safely operate and work on the device/s at all hours, unless otherwise agreed by the Distributor.

2727



SPDs and Assemblies

SPD/s and the assemblies shall in part:- (a) be of a type acceptable to the Service and Installation Rules

Management Committee or the relevant Distributor; conform to the requirements of the appropriate Australian or

International Standard for the type of device employed; (c) be installed in accordance with the requirements of the

Electricity Safety Act, Regulations and these Guidelines; (d) be installed so as to comply with the minimum height

requirement of consumers terminals connected to the distributors service cables,

2828



be selected with regard to the conditions, taking account of the nature of the supply (i.e. overhead, underground):

(f) have a rated short circuit current capacity equal to or greater than the prospective short circuit current at the point it is installed;

(g) have, or be installed with, facilities for sealing un-metered connections to prevent unauthorised access;

(h) be maintained by the customer in accordance with the manufacturers specifications.

Fused Switch Disconnector (FSD)

Stick operated FSDs shall be suitable for mounting on either a pole or building faade

Hand operated FSDs shall be suitable for mounting within the standard service connection facility

3232



Prohibited Fuses

Stick Operated, Panel Mounted Fuses are a specific form of panel mounted fuse originally designed for mounting on a connection box mounted on the underside of a shop veranda.

These fuses are no longer acceptable for use as an SPD or occupancy disconnection device for new connections, alterations or additions to existing electrical installations.

3333


Changes - Section Six (6).Supply Capacity Control Device.

Supply Capacity (Maximum Demand by Limitation)

Supply Capacity Control Device (SCCD)

Capacity Control and types Electrical installations shall be arranged in accordance with the Wiring Rules

so as not to exceed 130% of the Distributors nominated supply capacity for more than 2 hours by one of the following means:

Moulded case circuit breakers with a fixed thermal trip unit setting of 130%.

Miniature circuit breakers with a fixed thermal trip unit setting of 145%.

These circuit breakers must be de-rated to achieve 130% of the nominated supply capacity.

Adjustable circuit breakers are acceptable provided the thermal trip unit is set to a level equal to the nominated supply capacity and the overload duration is set as agreed with the distributor.

3434



Maximum Demand Limitation Device/s (SCCD) Circuit breakers shall:

Be installed on the main switchboard in accordance with the Electricity Safety Act and Regulations, the Wiring Rules, and these Rules;

Be arranged to ensure the aggregate rating of the devices does not exceed the supply capacity where multiple devices are used; and

Be provide with a sealing facility when adjustable.

3535



Supply Capacity Control Device SCCD

The 2009 Safety Installation Regulations no longer permit a switch ahead of the Installation Main Switch/s.

-Therefore the SCCD cannot be located on the meter panel or meter board and shall be the Main Switch or the summation of the Main Switches, where multiple main switches are used.

3636



Consumers Mains Overload and Short Circuit requirement

As per Clause 2.5.1.1 of AS/NZS3000:2007 consumers mains are to have overload and short circuit (overcurrent) protection.

This is best achieved by using circuit breaker/s as the Main Switch or summation of the Main Switches to be equal to or less than the current carrying capacity of the consumers mains.

Hint. Use the main switch/es as both consumers mains protection and the distribution companies SCCD.
