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.
The NEC also permits grounding-type receptacles in non-grounded wiring protected by a GFCI; this only applies when old non-grounded receptacles are replaced with grounded receptacles, and the new receptacles must be marked with 'No equipment ground' and 'GFCI Protected' . 240 V receptacle faces
The grounding wire would be diverted around the adapter to reach the faceplate screw above it. However, this ground-wire style of cheater plug was discontinued when it was noted that a loose unattached grounding wire could accidentally become connected to the "hot" blade of a nearby outlet, potentially leading to electric shock. As an ...
Ground is a safety conductor with a low impedance path to earth. It is often called the "ground wire," or safety ground. It is either bare or has green insulation. [1] Leg as in "hot leg" refers to one of multiple hot conductors in an electrical system.
A receptacle with a bootleg ground. In building wiring installed with separate neutral and protective ground bonding conductors (a TN-S network), a bootleg ground (or a false ground) is a connection between the neutral side of a receptacle or light fixture and the ground lug or enclosure of the wiring device.

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
A woman who has sat in prison for more than a decade was released Tuesday after new evidence contradicted accounts that she helped a hitman take out an innocent victim 25 years ago in the Bronx.
A wire break in the fault to load section, or in the earth to ground section, will disable operation of the ELCB. Requirement of an additional third wire from the load to the ELCB. Separate devices cannot be grounded individually. Any additional connection to Earth on the protected system can disable the detector.
