What color is the neutral wire in the distribution box

The neutral wire should be white or light gray in the United States according to NEC standards. In North America, the neutral wire is designated by a white or light gray insulation to clearly distinguish it from hot (live) wires, which are typically black, red, or blue, and from the grounding conductor, which is green, green with a yellow stripe, or bare copper (NEC Article 200. 6 and 250.

119). This color coding ensures that anyone working on the distribution box can safely identify the return path for current, preventing accidental contact with live wires and reducing the risk of electrical hazards. For higher voltage commercial systems, such as 277/480V AC, gray insulation may be used for the neutral conductor to differentiate it from standard residential 120/240V white neutrals.

International variations: In many European countries following IEC standards, the neutral wire is typically blue, so it is important to verify local regulations if working outside the U. S.. Safety tip: Always ensure the power is turned off and verify wire identification with a tester before connecting any wire in a distribution box.

Using the correct color for the neutral wire is not just a convention—it is a critical safety requirement to prevent miswiring and potential electrical accidents.
