Historically, has been referred to as , because the voltage range starts in the two-twenties. A house will have two phases of hot wires while also having a neutral for recycling unused electricity and a ground wire — in newer homes for safety reasons. There are two primary types of plugs.
In countless cases, these appliances most often water heaters, furnaces, and ovens are hard-wired, meaning you cannot unplug them. To unplug, or change the wiring, you must unbolt the wiring nuts from the appliance.

These four prongs in the contemporary plug are made up of two hot prongs Phase A and Phase B , one neutral wire prong, and one ground wire prong.
