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 ...
The ground tab is designed to be attached to the outlet faceplate screw, which is supposed to be connected to the building electrical ground. A cheater plug , AC ground lifter or three-prong/two-prong adapter is an adapter that allows a NEMA 5-15P grounding -type plug (three prongs) to connect to a NEMA 1-15R non-grounding receptacle (two slots).

An earth-leakage circuit breaker (ELCB) is a safety device used in electrical installations to prevent shock.It consists of either a current sensing mechanism, or a voltage sensing mechanism.
A 120 volt combination AFCI/GFCI receptacle. Unlike circuit breakers and fuses, which only open the circuit when the current exceeds a fixed value for a fixed time, a GFCI device will interrupt electrical service when more than 4 to 6 milliamperes of current in either conductor leaks to ground.
NEMA 1-15P (two-pole, no ground) and NEMA 5-15P (two-pole with ground pin) plugs are used on common domestic electrical equipment, and NEMA 5-15R is the standard 15-ampere electric receptacle (outlet) found in the United States, and under relevant national standards, in Canada (CSA C22.2 No. 42 [1]), Mexico (NMX-J-163-ANCE) and Japan (JIS C 8303).
A receptacle tester being used to check for some types of improper wiring of an outlet. For this particular tester, proper wiring is indicated by the two yellow lights. The outlet tester checks that each contact in the outlet appears to be connected to the correct wire in the building's electrical wiring. It can identify several common wiring ...
He also invented the ground-fault circuit interrupter or GFCI in 1961. [1] The GFCI is commonly found in home bathrooms or kitchens. The device operates normally until 5 milliamps passes from the appliance to ground. Charles Dalziel was a pioneer in understanding electric shock in humans. Dalziel married Helen Bradford in 1931.
