What is a duplex outlet?

A duplex outlet, also known as a double outlet, is a type of electrical outlet that features two receptacles in the same unit. This allows for two separate devices to be plugged in and powered simultaneously from the same outlet. Duplex outlets are commonly used in homes and businesses to provide multiple electrical connections in one location.

Duplex outlets are typically installed in walls or surfaces and have two vertical slots for standard plug prongs, as well as a round hole for grounding. They are usually designed to accept Type A and Type B plugs, which are the most common types of plugs used in North America.

It is important to note that duplex outlets should be installed by a qualified electrician to ensure proper wiring and safety compliance. Additionally, using extension cords or power strips with duplex outlets should be done with caution to avoid overloading the circuit and causing a potential fire hazard.
