Which wiring color serves as the neutral in electrical systems?

In electrical systems, the color white or gray is designated as the neutral wire. The role of the neutral wire is to carry current away from the load and back to the electrical panel, completing the circuit. It provides a return path for current to flow safely, facilitating the normal operation of electrical devices.

The use of white or gray for neutral wiring is part of standardized color coding for electrical installations, which helps ensure safety and prevent confusion during wiring tasks. This standardization is crucial, particularly in residential and commercial electrical systems, as it helps electricians and anyone working with electrical components easily identify the function of each wire.

The other colors mentioned, like black and red, are typically used for hot wires, which carry electrical current from the power source to the load. Green is universally recognized as the color for ground wires, which provide a path for electricity to dissipate safely in case of a fault. Thus, identifying the wiring colors accurately is essential for the safe installation and maintenance of electrical systems.
