About Power Connectors
Power connectors transfer alternating current (AC) or direct current (DC) through a variety of electronic devices. They are used in many residential, general-purpose, commercial, industrial, laboratory, and hospital applications. Several types of power connectors are available. Receptacles, outlets, and jacks are female power connectors into which plugs or male connectors are inserted to make circuit connections. Power entry modules, another type of connector, typically mount on the case or panel of a machine and attach to a power cord. Some power entry modules serve as switches, fuses, or filters. Others serve as circuit breakers or indicator lights.
Important specifications for power connectors include number of poles and grounding method. Typically, power connectors have between one and five poles. The grounding method determines the path that electricity follows when moving from a defective connector back into the earth. Some electrical circuits provide an embedded ground terminal. Others establish a connection to an existing grounding path such as ducting or structural steel. Power connectors with a ground fault circuit interrupter (GFCI) include a built-in circuit that detects leakage current to ground and interrupts power to prevent electrical hazards. Isolated ground circuits provide a clear grounding path to the service panel.
