There are several alternatives for connecting newer appliances to two-prong receptacles without rewiring the building: removing the grounding pin of the plug (unsafe), replacing the receptacle with a three-prong outlet (unsafe without proper ground), or replacing the receptacle with a Ground Fault Circuit Interrupter (GFCI).
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 ...
Some receptacle testers include an additional test button to test the triggering of GFCI devices, which supplements the built-in test button on the GFCI and can be used for testing outlets downstream from a GFCI receptacle. "Plug-in analyzers" may include earth loop impedance and other checks. [5]: 48–49
A branch type AFCI trips on 75 amperes of arcing current from the line wire to either the neutral or ground wire. A combination type adds series arcing detection to branch type performance. Combination type AFCIs trip on 5 amperes of series arcing. Dual-function AFCI GFCI (ground fault circuit interrupter) 110 volt receptacle circa 2016
Another cause of nuisance tripping is due to accumulated or burden currents caused by items with lowered insulation resistance. This may occur due to older equipment, or equipment with heating elements, or even wiring in buildings in the tropics where prolonged damp and rain conditions can cause the insulation resistance to lower due to ...
A North American power strip with two USB power ports that includes a built in surge protector. A power strip (also known as a multi-socket, power board and many other variations [a]) is a block of electrical sockets that attaches to the end of a flexible cable (typically with a mains plug on the other end), allowing multiple electrical devices to be powered from a single electrical socket.
The reduced diameter conductors in the flexible cords connecting an appliance to the plug intended for use with sockets on a ring circuit are individually protected by a fuse in the plug. Its advantages over radial circuits are therefore reduced quantity of copper used, and greater flexibility of appliances and equipment that can be connected.
Tripping the Rift is an adult CGI science fiction comedy television series. It is based on two short animations published on the internet by Chris Moeller and Chuck Austen . The series was produced by CinéGroupe in association with the Syfy network.
