This document discusses the electricity supply system in the Philippines. It describes the key components which include generation of power using various energy sources, transmission of power at high voltages via transmission lines, distribution of power at lower voltages to end users via local grids, and utilization of power by consumers. It also outlines the customer classes in the system and recent changes to better classify customers. Electrical safety tips are provided to help prevent accidents from careless or improper use of electricity.

20. CONTROLLING ELECTRICAL FIRE
ELECTRICAL SAFETY

21. CAUSES OF ELECTRICAL
ACCIDENTS
There are 3 major causes of electrical accidents:
Carelessness, misuse, ignorance
PROCLAMATION NO. 193 (Pres. Benigno Aquino)
- The primary cause of fire is “not faulty electrical wiring but
the ignorance in the use of electrical appliances and
gadgets such as overloading of electrical outlets and the
use of counterfeit electrical products such as circuit
breakers, power strips, extension cords, batteries &
holiday lights that cause fires, explosions, shocks, and
electrocution”

22. The Bureau of Fire Protection (BFP)
 identifies “octopus connections” – several
electrical appliances are connected to 1 outlet,
resulting in power overload and other electrical
faults – as main cause of fires in the home.
Avoid having such connections in your house

It is better to be careful
100 times
than to get killed once.
