A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...
As of the 2020 NEC this exception no longer exists and those devices in are required to have GFCI protection where otherwise required. Two-wire outlets having no grounding conductor may be protected by a GFCI or one upstream of the receptacle and must be labelled "No Equipment Ground" and "GFCI Protected". Most GFCI receptacles allow the ...
A safer and more reliable alternative identified in the US and Canadian electrical codes is to replace the outlet with a Ground Fault Circuit Interrupter (GFCI) breaker outlet. [3] Cheater plugs are also used to break ground loops in audio systems. [5] This practice has been condemned as disregarding electrical safety.
[citation needed] A connector with ground terminal has more wires than poles: two-pole, three-wire; or four-pole, five-wire; etc. A non-grounded device may be two-pole, two-wire; three-pole, three-wire; etc. [citation needed] The numerals following the hyphen is the current rating of the device in amperes.
One GFCI receptacle can serve as protection for several downstream conventional receptacles. GFCI devices come in many configurations including circuit-breakers, portable devices and receptacles. Another safety device introduced with the 1999 code is the arc-fault circuit interrupter (AFCI).
BS 546, "Two-pole and earthing-pin plugs, socket-outlets and socket-outlet adaptors for AC (50-60 Hz) circuits up to 250 V" describes four sizes of plug rated at 2 A, 5 A (Type D), 15 A (Type M) and 30 A. The plugs have three round pins arranged in a triangle, with the larger top pin being the earthing pin.
