Duplex Receptacle

Definition and meaning of Duplex Receptacle in real estate.

A duplex receptacle is a standard electrical outlet designed to accommodate two separate electrical plugs simultaneously.

In more detail

It is the most common type of electrical outlet found in modern homes, typically mounted in a wall box and wired to a household circuit. Each of the two outlets in the receptacle has hot, neutral, and ground slots to safely distribute electricity to appliances and lighting.

In areas exposed to moisture, such as kitchens, bathrooms, and outdoor spaces, these receptacles must feature ground fault circuit interrupter protection to prevent electrical shocks. Understanding the location and capacity of these receptacles is important during home inspections to ensure the electrical system meets local safety codes.

Frequently asked questions

What is a tamper-resistant duplex receptacle?

It is a safety outlet with built-in spring-loaded shutters that block foreign objects, such as keys or bobby pins, from being inserted unless equal pressure is applied to both slots simultaneously.

Can you wire a duplex receptacle so only one outlet is controlled by a wall switch?

Yes, by breaking the metal tab connecting the two brass terminals on the side of the receptacle, an electrician can wire one outlet to be always hot and the other to be controlled by a switch.
