What color or markings must an insulated grounded conductor of 6AWG or smaller have?

An insulated grounded conductor of 6AWG or smaller must be identified by a continuous white or gray outer finish, or it can have three white stripes. This color coding is established by the National Electrical Code (NEC) and is designed to ensure that these conductors are easily identifiable and distinguishable in an electrical system. The use of white or gray indicates that the conductor is neutral, providing critical information for safety and proper electrical functioning.

In the context of various electrical installations, proper identification of grounded conductors is essential to prevent accidental connections or mistakes that could lead to short circuits or electrical shocks. Therefore, the standardization of these color markings plays a vital role in maintaining safety and compliance with electrical codes.
