Engr. HIPOLITO A. LEONCIO Chairman, Electrical Safety and ESEA committee

Electricity is an essential part of

our development

No nation can survive the

present developmental challenges

without POWER

Backgrounder

Electric power should not only

be available, realiable and

affordable, but above all SAFE.

One of the primary advocacies of

IIEE is ELECTRICAL SAFETY!

Backgrounder

Engineering is all about safety. One of

IIEE Safety Program is the signing of a

MOA with our industry partners. e.g.

The International Copper Industry

Association of Southeast Asia (ICIASEA)

Backgrounder

This brought about the creation of

ESEA (Electrical Safety Enforcement and

Awareness)

Presidential Executive Order # 193

declares that every month of every year

is ELECTRICAL SAFETY MONTH.

Backgrounder

On May 28, 2015, a joint project of IIEE and

MERALCO will conduct the 2nd Electrical Safety

Summit

The event will highlight the concerted effort

of IIEE and MERALCO of the importance of

electrical safety to our citizen.

2nd Electrical Safety Summit

Statistic from the Bureau of

Fire of the Philippines (BFP)

shows that 35% of the cause

of fire is electrical related.

FIRE CAUSES

Though their reason is “FAULTY

ELECTRICAL WIRING”

Need regular electrical

inspection of work places and

residences.

FIRE CAUSES

Electrical safety should a

primary concern of all electrical

engineers and practitioners and

manufacturers.

ELECTRICAL SAFETY

Philippine Electrical Code (PEC)

should at all time be followed

and impose!

PEC

“ELECTRICAL SAFETY

STARTS WITH ME”

ELECTRICAL INSPECTION STRATEGY AND GUIDE

• Republic Act 7920

An act providing for a more responsive and comprehensive regulation for the practice, licensing, and regulation of electrical engineers and electricians

STRATEGIC SOLUTIONS The Philippine Electrical code

is used nationally as the

basis for safeguarding

persons, buildings and its

contents from hazards that

may arise from the use of

electricity.

This code contains provisions

which is considered

necessary for safety and thus

is used as basis for the legal

enforcement agency in the

government regarding

electrical installation

WHAT IS AN ELECTRICAL INSPECTION & AUDIT?

• An electrical audit is a thorough survey/ inspection, review and evaluation of an electrical system which is already in operation for several years.

WHAT IS THE PURPOSE OF AN ELECTRICAL INSPECTION &

AUDIT? • The purpose of an electrical safety inspection or audit is to identify potentially hazardous electrical situations and provide corrective actions for these situation.

OBJECTIVES of ELECTRICAL

INSPECTION & AUDIT - 1

• # 1. Determine compliance of the electrical system to electrical safety, viz-a-viz:

- Philippine Electrical Code (Part I & II)

- National Electrical Code - NFPA 70E - NFPA 70B - OSHA 1910.331-335

- Other Electrical Codes (IEC)

OBJECTIVES OF AN ELECTRICAL

INSPECTION & AUDIT – 2,3,4

• #2. Review and provide corrective actions for

safe electrical work processes.

• # 3. Review and provide corrective measures for electrical maintenance tools.

• # 4. Identify efficient measures and potential cost savings through modifications/ improvements in the electrical system.

• So what would be the samples of electrical violations or errors that you should be mindful of when you do your electrical audit/ inspections?

1. THE USE OF HIGHER RATED CIRCUIT PROTECTION . . . THIS IS A RAMPANT VIOLATION!

1-A. ANOTHER CASE OF USING VERY HIGH RATING OF PROTECTION..

AS INSPECTED IN 2011, THE SIZE OF THIS SERVICE ENTRANCE FEEDER IS 2 – 14 SQUARE MM IN A PVC CONDUIT, SO THAT THE ALLOWABLE AMPACITY IS

70 AMPERES BUT THE PROTECTION IS 200-AMPERE FUSES!

THE IIEE ESC/ESEA VOLUNTEER TEAM IN 2012 REPLACED IT WITH 100-AMPERE FUSES.

2. INADEQUATE EQUIPMENT GROUNDING . .

WHAT WOULD BE THE MAXIMUM GROUNDING RESISTANCE? IS IT 25 OHMS?5 OHMS?1 OHM? THE LOWER THE VALUE, THE SAFER! WHY? GROUND FAULT CURRENT SEEKS THE PATH OF LOWER RESISTANCE.

3. NOT USING GROUNDING TYPE CONVENIENCE OUTLETS . . .

4. NOT USING GFCI DEVICE FOR CIRCUITS IN

DAMP LOCATIONS OR EXTERIOR AREAS . .

5. NOT CHECKING THE BUS BAR CAPACITY OF THE PANEL BOARDS/ BUS BAR GUTTERS . .

6. FAILURE TO TEST COMPLETELY BEFORE ENERGIZATION

• AFTER A PROLONGED SHUTDOWN OF A SWITCHGEAR, A DANGEROUS ARC FLASH FAULT BETWEEN PHASES MAY RESULT AFTER ENERGIZATION OF THE BUS BARS!

• THIS MAY HAPPEN WHEN THERE IS A FAILURE TO

DETERMINE THE INSULATION RESISTANCE OF THE ENCLOSED

BUS BARS.

• AFTER A PROLONGED SHUTDOWN ON A HUMID DAY, MOISTURE MAY OCCUR DUE TO CONDENSATION INSIDE THE SWITCHGEAR.

• WARNING: ALWAYS MEGGER TEST CIRCUIT BREAKERS, BUS

BARS, CABLE FEEDERS BEFORE ENERGIZATION!

• THE HIGHER THE MEGGER READING, THE SAFER!

7. USING IMPROPER SPLICES

8. NOT USING SEAL FITTINGS IN HAZARDOUS LOCATIONS…

NOTE THAT THERE ARE NO TYPE “EYS” CONDULET SEAL FITTINGS ON THE CONDUITS WITHIN 150MM FROM THE

SWITCH BOXES.

IN CLASSIFIED LOCATIONS, THE CONDUIT SEAL WOULD

PREVENT THE ENTRY OF FLAMABLE GASES OR VAPORS TO THE SWITCHES WHICH ARE

POSSIBLE SOURCES OF A SPARK.

9. LACK OF SUPERVISION DURING CONSTRUCTION…

THESE INAPPROPRIATELY/POORLY SPLICED WIRES INSIDE A BADLY BURNT FLEXIBLE PVC CONDUIT. THE ELECTRICAL SUPERVISOR/FOREMAN MISSED THIS.

10. TEMPORARY WIRING ALLOWED TO BECOME TEMPORARY-PERMANENT

THE FLYING WIRES/CABLES WHICH INCLUDE POWER & COMMUNICA-TION LINES ARE INSTALLED TEMPORARILY.. UNTIL AN UNTOWARD INCIDENT HAPPEN AGGRAVATING MATTERS – ACCIDENTS.

11. NOT USING SEAL FITTINGS IN HAZARDOUS LOCATIONS…

NOTE THAT THERE ARE NO TYPE “EYS” CONDULET SEAL

FITTINGS ON THE CONDUITS WITHIN 150MM FROM THE

SWITCH BOXES.

IN CLASSIFIED LOCATIONS, THE CONDUIT SEAL WOULD

PREVENT THE ENTRY OF FLAMABLE GASES OR VAPORS TO THE SWITCHES WHICH ARE

POSSIBLE SOURCES OF A SPARK.

12.LACK OF SAFETY SENSE…

NOTICE THE SERVICE ENTRANCE WIRES, NO ENTRANCE CAP OR DRIP LOOP – THIS ALLOWS WATER TO ENTER CONDUIT AND MAY EVEN REACH PANELBOARD INSIDE, CAUSE DAMAGE, OR GROUND FAULT. THERE IS ALSO NO GROUND WIRE.

13.NOT USING BOLT-ON TYPE MAINS THE 60A PANEL MAIN CBs ARE PLUG-IN TYPE, SHOULD BE BOLT-ON TYPE..

THE PLUG-IN MAINS WILL RESULT TO LOOSE CONNECTION, LOCALIZE HEATING..

14. LACK OF MAINTENANCE

REGULAR CLEANING

REQUIRED.

CABLE

TERMINATIONS

ARE VIOLATIONS.

COLOR CODING OF

WIRES MUST BE

FOLLOWED.

15. JUNCTION BOX COVER MISSING ..

THE ABSENCE OF THE COVER FOR THE JUNCTION BOX EXPOSES THE CONDUCTORS NOT ONLY TO WATER BUT ALSO TO THE ULTRA-VIOLET (UV) RAYS OF THE SUN, CAUSING THE DETERIORATION OF THE INSULATION OF

THE CONDUCTORS FASTER.

16. Panel Cover & Power CBs Not Fitted Properly…

In a big manufacturing plant, during the retrofitting or replacement of the main circuit breaker of the Low Voltage Switchgear, the panel opening is so big where in there is a large clearance between the front face of new power breaker and the panel opening. This may allow foreign bodies such as dust, and even live creatures to possibly enter inside the switchgear and cause a shutdown. A control wire is even left not tied properly.

17. Old Fused Disconnects Still in Use?

The use of old fused disconnect switches where in the load side feeder wires are

too small in their ampacities as matched to the rating of the fuses. The fuses may protect

the small wires from high magnitude short circuit current but not on an overload current

or during a low magnitude line-to-ground fault. These

installations must be replaced with bus bar type panel board

of power distribution to various load circuits.

18. Cables Not Provided w/ Raceways..

Would you believe that this kind of cable installation still exists? If you are the electrical practitioner assigned to supervise the electrical works, how would you have provided for a better job?By providing flexible metallic conduits?By a cable duct?Or by extending the cable trench?

19. POOR VENTILATION FOR HEAT GENERATING EQUIPMENT

THE TRANSFORMER BELOW WHICH WAS INSTALLED INSIDE A CABINET THAT IS NOT ADEQUATELY VENTILATED OR NOT PROVIDED WITH LOUVERS SHOWS SIGNS OF EXCESSIVE HEAT BEING DISSIPATED. IT WAS SOON DAMAGED

AS-BUILT PLANS • After your thorough electrical inspection & audit,

you will now prepare/ update your electrical drawings:

* Lighting Layouts * Power Layouts * Panel Arrangements * Single Line Diagram/ Riser Diagram * Load Schedules and Computations * Service Entrance

* Substation * Meter Center * Grounding system * Lightning Protection system * Other electrical details of

the electrical system

Note down all observations of non-compliance/ Code violations, unsafe situations, inefficient

system/ equipment, etc…
