  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, 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 ...

  3. 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.

  4. NEMA connector - Wikipedia

    en.wikipedia.org/wiki/NEMA_connector

    Per UL Standard ANSI/UL 498, a receptacle (any color) with an orange triangle, is an isolated ground (IG) device, where the grounding pin of the receptacle is connected to ground independently of the frame of the receptacle and wiring outlet box. This is also a requirement of the National Electrical Code (NFPA 70), Article 406.

  5. 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

    Ground-fault circuit interrupter (GFCI) protection is required on receptacles in wet locations and locations where there exists an easy path for fault current to travel to earth. This includes all receptacles intended to service kitchen counter surfaces, crawl spaces at or below grade level, basements, garages and accessory buildings, bathrooms ...

  7. Electrical outlet tester - Wikipedia

    en.wikipedia.org/wiki/Electrical_outlet_tester

    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 ...

  8. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

  9. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
