2. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   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.

3. Arc-fault circuit interrupter - Wikipedia

   en.wikipedia.org/wiki/Arc-fault_circuit_interrupter

   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

4. Three-prong adaptor - Wikipedia

   en.wikipedia.org/wiki/Three-prong_adaptor

   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.

5. Electrical wiring in North America - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring_in_North...

   This device, which can be a circuit breaker or the first outlet on a circuit, is designed to detect hazardous electrical arcing in the branch circuit wiring as well as in cords and plugs. An AFCI device is designed to trip quickly when it detects potentially dangerous arcing that could start a fire, but not trip with harmless arcing as part of ...

6. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   A shunt-trip unit appears similar to a normal breaker and the moving actuators are ganged to a normal breaker mechanism to operate together in a similar way, but the shunt trip is a solenoid intended to be operated by an external constant-voltage signal, rather than a current, commonly the local mains voltage or DC. These are often used to cut ...

7. Bootleg ground - Wikipedia

   en.wikipedia.org/wiki/Bootleg_ground

   In addition, a fault condition to a bootleg ground will not trip a GFCI breaker, nor protect a receptacle that is wired from the load side of a GFCI receptacle. [2] Before 1996, in the United States it was common to ground the frames of large 120/240-volt permanently-connected appliances (such as a clothes dryer or oven) to neutral conductors.

   A pregnant woman is recovering in the hospital after she was stabbed multiple times by a pizza delivery driver over the size of her tip, according to reports. The incident happened on Sunday, Dec ...

9. Arc flash - Wikipedia

   en.wikipedia.org/wiki/Arc_flash

   The circuit breaker closest to the downstream fault will send a restraining signal to prevent upstream breakers from tripping instantaneously. The presence of the fault will nevertheless activate the preset trip delay timer(s) of the upstream circuit breaker(s); this will allow an upstream circuit breaker to interrupt the fault, if still ...
