Which is an acceptable means of identification of the equipment grounding conductor terminal on a duplex receptacle?

The identification of the equipment grounding conductor terminal on a duplex receptacle is clearly indicated by a green-colored finish. This standard color coding is crucial for ensuring that electricians and maintenance personnel can easily and correctly identify grounding connections during installation and troubleshooting. Green is universally recognized for grounding, aligning with the National Electrical Code (NEC) and safety practices in electrical work.

Using green for grounding helps prevent dangerous mistakes that could arise from misidentification, ensuring that grounding conductors are properly connected to provide a safe path for electrical faults. Each color in electrical work serves a specific purpose and promotes uniformity across electrical installations, reinforcing safety protocols and helping to avoid confusion in identifying electrical systems.
