A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating leakage current to ground or current flowing to another powered conductor.
Diary of a Camper is an American short film released in October 1996 that was made using id Software's first-person shooter video game Quake.The film was created by the Rangers, a clan or group of video game players, and first released over the Internet as a non-interactive game demo file.
These may either contain two or three tripping mechanisms within one case or, for small breakers, have the breakers externally tied together via their operating handles. Two-pole common-trip breakers are common on 120/240-volt systems where 240 volt loads (including major appliances or further distribution boards) span the two live wires.

A circuit breaker is used as a protection device to interrupt fault currents automatically, and may be used to switch loads on and off, or to cut off a line when power is flowing in the 'wrong' direction. When a large fault current flows through the circuit breaker, this is detected through the use of current transformers. The magnitude of the ...
