A 240-volt outlet is a type of electrical outlet that delivers higher voltage than standard outlets. It is commonly used for large appliances, such as electric dryers, ovens, and air conditioners. These outlets have four slots to accommodate both hot wires (120 volts each), a neutral wire, and a ground wire.

A 240-volt outlet, also known as a 220-volt outlet, is a type of electrical socket that delivers higher voltage to power specific appliances and devices. Unlike standard outlets, which use a single 120-volt cable, 240-volt outlets consist of two 120-volt cables and a neutral wire.

What is a 240-Volt Outlet? One standard electrical outlet contains a 120-volt wire and a neutral wire which deliver power using one phase of your electrical service. 240-volt outlets use two 120-volt wires simultaneously, plus a neutral wire to power a single receptacle. Older homes and appliances may use three-prong 240-volt outlets.

A standard volt outlet in any household provides 120 volts of electricity. However, a 240-volt outlet provides two 120-volt wires at the same time for running larger appliances like ovens, dryers, air conditioners, and some large power tools that require more power to operate.

A 240 volt outlet is larger with two vertical side holes, an “L”-shaped hole on top, and a bottom hole that looks like a half circle. Newer four-prong outlets add a ground wire over older three-pronged ones that helps avoid electrical shock. A 240-volt outlet is typically about 4½ inches high and 4½ inches wide.
