How can insulated grounded conductors of sizes 6 AWG and smaller be identified?

Insulated grounded conductors that are sized 6 AWG and smaller are identified by a continuous green color. This is consistent with the NEC (National Electrical Code) requirements, which specify that green conductors are used for grounding purposes. The green color serves as a universal standard for identifying grounded or grounding conductors, helping ensure safety and consistency across electrical installations.

Using a continuous green color allows electricians and inspectors to easily recognize the purpose of the conductor in a circuit, minimizing the risk of mistakes during installation or maintenance. The other color options listed do not serve this identification purpose as effectively; for instance, white typically designates neutral conductors, while brown and black are used for ungrounded conductors. Thus, identifying grounded conductors with a continuous green color is crucial for maintaining electrical safety and adherence to industry standards.
