In general, the equipment grounding conductor terminal on a receptacle or switch is identified by which of the following?

• A. A Green-Colored Hexagonal Terminal Nut That Cannot Be Easily Removed
• B. A Green-Colored Pressure Wire Connector
• C. A Green-Colored Terminal Screw Provided with a Hexagonal Head That Cannot Be Easily Removed
• D. Any of the Above

Answer: (D)

Grounding connections on receptacles and switches are marked with green to identify the equipment grounding terminal. That green marking can show up on different hardware depending on the device design: a green hexagonal terminal nut, a green pressure wire connector, or a green terminal screw with a hex head. Because all of these are green and serve as the grounding point for the equipment grounding conductor, any of them could be the terminal used for grounding. The key idea is the color code and its purpose, not the specific hardware form.
