A pin socket, in the context of electrical power, is a female receptacle designed to receive a male plug, typically with protruding pins, to establish an electrical connection. These sockets are commonly found in walls or on devices and are used to connect appliances and other electrical equipment to the power supply. They usually have two or three receptacles, one for the live (or hot) wire, one for the neutral wire, and sometimes a third for the ground wire (earth).
