Known as one of the oldest and most important electrical coding systems, color coding for electrical wires in the US is used to indicate the voltage, amperage, insulation material, and other safety information needed for the proper operation of any electrical wiring. This system of color coding helps electricians and homeowners alike to safely work with electricity by clearly indicating the dangers associated with each wire.
The color coding system for electrical wires in the US began in the early 1900s, and has since been adopted by many countries around the world. The system was initially developed by the American Institute of Electrical Engineers, and it is still used today in order to help electricians to quickly identify a wire’s function and purpose. There are two main categories of color coding in the US: the National Electric Code (NEC) and the Industrial Standard Wiring Color Code (IEC).
The NEC color code is used in residential and commercial buildings, while the IEC color code is widely used in industrial and factory settings. Each code assigns different colors to identify the type of wire, as well as the purpose of its use. As an example, red wires are usually used for hot wires while black wires are often neutral. Understanding the color codes for electrical wires in the US makes it easier for electricians and homeowners to both install and maintain their electrical systems safely.
