The neutral wire in a building electrical system is usually what color?

In residential and commercial electrical systems, the neutral wire is typically color-coded white. This standardization is important for safety and consistency in electrical wiring. The neutral wire serves as a return path for electric current, completing the electrical circuit. By using a specific color, electricians and home inspectors can easily identify the neutral wire and ensure it is correctly connected.

The other colors associated with wires serve different purposes in the electrical system. For example, green is reserved for grounding wires, black is commonly used for hot wires that carry current, and bare copper wires also represent grounding conductors. Knowing these color codes helps prevent accidents and ensures that electrical systems are installed correctly and safely.
