What color is the acceptable identifier for the equipment grounding conductor terminal on a duplex receptacle?

The acceptable identifier for the equipment grounding conductor terminal on a duplex receptacle is green. This color convention is standard in electrical wiring and is essential for safety. The use of green for grounding conductors helps ensure that electricians and anyone working with electrical systems can easily identify which conductors are designated for grounding.

Grounding is crucial because it helps prevent electrical shock and enables the safe operation of electrical equipment by providing a path for fault currents to travel back to the ground instead of passing through a person. This identification through color coding aids in preventing mistakes during installation or maintenance, enhancing overall safety in electrical systems.
