Question:
We are having an argument about duplex receptacles and we are hoping you can clarify. Is a duplex receptacle one or two receptacles. It mounts in a single-gang box.
Please provide any applicable Code reference.
Thanks,
Scott Anton

Answer:
Hi Scott, thanks for the question.
We get that question a lot. That and which way does the ground go on a receptacle installation, up or down.
The answer to your question is that a duplex receptacle on a single mounting strap (yoke) is two receptacles (contact devices) mounted on the same mounting strap. The Code refers to this as a multiple receptacle on a single yoke. The definition of the term receptacle and the new informational note in Article 100 of the 2020 NEC help provide the apparent needed clarification.
