The Philippine Electrical Code (PEC) is the country’s official guide to wiring and electrical installation. It contains a set of regulations and standards that govern all electrical activities within the Philippines. One important aspect of the PEC is the color of wires. This guideline ensures that workers and engineers can identify the different types of conductors in a wiring system. By using the correct color of wires, it will be easy for them to diagnose and troubleshoot any possible issues with the wiring system.
The Philippine Electrical Code specifies the color of wire for residential and commercial installations. The standard colors for residential use are black, white, green, and blue. Black and white are used for the hot and neutral wires respectively. Green is used for the ground wire while blue is used for the switched hot wire. For commercial installations there are five colors used: black, white, red, yellow, and green. Black and white are still used for the unswitched hot and neutral wires while red is used for the switched hot wire. Yellow is used for the protective ground wire while green is used for the equipment ground wire.
Knowing the correct color of wires is essential for electricians, engineers, and other professionals that work with wiring systems. It helps to ensure a safe and properly working installation. Following the Philippine Electrical Code’s color guidelines will help to prevent any confusion when dealing with different wiring systems. It also serves as a reminder to engineers and electricians to correctly identify the different conductors and to make sure they are connected to the right terminals.
