What should be the color for the identification of equipment grounding conductors for sizes 6 AWG and smaller?

The identification of equipment grounding conductors, especially those that are 6 AWG and smaller, is standardized to ensure consistency and safety across the electrical installation industry. The correct color for this identification is continuous green with yellow stripes. This specific coloring signifies that the conductor is intended for grounding purposes, helping electricians and inspectors quickly identify its function.

Using continuous green exclusively or just green and yellow without proper striping for grounding conductors maintains a clear visual distinction from other conductors. This coloring helps prevent accidental disconnection or misuse, especially in complex wiring systems, thereby enhancing safety protocols during installation, maintenance, and repairs.

While the other color options are used for different purposes, such as neutral conductors (which are typically white) or other phase conductors (which could be red or blue), the specific standardization of green with yellow stripes for grounding serves a unique role in electrical systems, making it critical for adherence to code requirements. Thus, the identification system is in place to promote safety and operational clarity.
