 Outlets in the kitchen, toilet, and bathroom, as well as those supplied by the ceiling for air-conditioning units do usually have a third grounding terminal, either in the form of a 3-pin outlet or a covered binding port.Devices designed for use with water, such as clothes washers and heated toilet seats, often have a separate earth wire or earth ground pin.Cheater plug adapters are readily available to convert such 3-pin plugs and so allow their use in all types of 2-pin sockets.
