What is the standard color code for a grounded conductor?

The standard color code for a grounded conductor is white. In electrical wiring systems, the grounded conductor, commonly referred to as the neutral wire, is designated by this color to clearly differentiate it from other conductors used for various purposes. This identification is essential for ensuring safety and preventing electrical shock when working with or around electrical systems.

The neutrality of the white wire allows it to return current to the electrical source safely, thus completing the circuit. Understanding this color code helps electricians and anyone working with electrical systems identify the purpose of each wire quickly and prevent potential errors during installation, maintenance, or troubleshooting.

The other color choices have distinct meanings: black is typically a hot conductor used for carrying current, red is often used for secondary hot wires in 240-volt circuits, and green is reserved for ground conductors, which provide a path to ground for electrical faults. Recognizing the specific function assigned to each color allows for adherence to safety standards and proper installation practices.
