Which of the following is a valid way to identify the equipment grounding conductor terminal on a duplex receptacle?

• A. Green-colored finish, the words green or ground, or the letters G or GR, or a grounding symbol
• B. A white color
• C. Not required to identify
• D. Blue marker

Answer: (A)

Grounding terminals on a duplex receptacle are identified by green coloring or clear labeling to distinguish them from the hot and neutral terminals. The green finish, or markings such as the words ground or green, the letters G or GR, or a grounding symbol, conform to standard electrical practices. This consistent identification helps ensure the equipment grounding conductor is connected correctly, which provides a safe path to earth during faults and reduces shock risk. The other options don’t fit because white is the color normally used for neutral, not grounding; claiming identification isn’t required goes against safety codes; and a blue marker isn’t the standard identifier for the grounding terminal and could indicate something else.
