A receptacle with spaces to plug in two cord caps is referred to as what kind of receptacle?

A receptacle designed to accommodate two cord caps is referred to as a duplex receptacle. This type of receptacle is commonly found in residential and commercial settings, allowing multiple devices to be plugged in simultaneously. The duplex design enables two cords to connect to the same electrical outlet, improving convenience and maximizing the use of available outlets without the need for additional hardware like extension cords.

In contrast, a single receptacle would only support one cord cap, while a quadruple receptacle would allow for four connections, and a triple receptacle would allow for three. Each of these other configurations serves different purposes but does not fit the description of a receptacle that accommodates two connections. The duplex receptacle is a standard fixture in electrical installations, making it essential for anyone working in electrical service to recognize and understand its function.
