What is true about receptacles and switches concerning equipment grounding conductor connection?

The answer is correct because receptacles and switches typically require a terminal for an equipment grounding conductor to ensure safety and proper functioning within electrical systems. The equipment grounding conductor provides a path for fault current to minimize the risk of electrical shock, fire, or equipment damage.

This grounding terminal allows the safe dissipation of excess electrical energy in the event of a fault, such as a short circuit. By connecting the equipment grounding conductor to the grounding terminal of a receptacle or switch, the electrical system adheres to the safety standards established by the National Electrical Code (NEC), making installations safer for both users and equipment.

In various configurations, such as three-prong receptacles, this grounding mechanism plays a crucial role in maintaining the integrity and safety of electrical appliances and fixtures.
