Duplex receptacles grounding contact orientation requirements according to the NEC are which of the following?

• A. There are no grounding contact orientation requirements in the NEC
• B. Top orientation required
• C. Bottom orientation required
• D. Horizontal orientation

Answer: (A)

The NEC does not regulate which way the grounding contact on a duplex receptacle must face. The important requirement is that the receptacle be properly grounded and securely mounted, with a continuous equipment grounding conductor connected to the grounding terminal. The orientation of the grounding contact—top, bottom, or horizontal—has no code-mandated position, so there are no grounding contact orientation requirements. This is why the correct understanding is that there are none. In practice, you can install the receptacle in any orientation as long as the grounding path and all other wiring and mounting rules are followed.
