    The National Electrical Code (NEC), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States. It is part of the National Fire Code series published by the National Fire Protection Association (NFPA), a private trade association . [ 1 ]

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

    As of the 2020 NEC this exception no longer exists and those devices in are required to have GFCI protection where otherwise required. Two-wire outlets having no grounding conductor may be protected by a GFCI or one upstream of the receptacle and must be labelled "No Equipment Ground" and "GFCI Protected".

  4. 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.

  5. NEMA connector - Wikipedia

    en.wikipedia.org/wiki/NEMA_connector

    All NEMA 6 devices are three-wire grounding devices (hot-hot-ground) used for 208 and 240 V circuits and rated for 250 V maximum, with the 6-15, 6-20 and 6-30 being grounding versions of the 2-15, 2-20 and 2-30, respectively. The 6-15 resembles the 5-15, but with collinear horizontal pins, spaced 23 ⁄ 32 in (18.3 mm) center-to-center. The 20 ...

  6. Three-prong adaptor - Wikipedia

    en.wikipedia.org/wiki/Three-prong_adaptor

    The ground tab is designed to be attached to the outlet faceplate screw, which is supposed to be connected to the building electrical ground. A cheater plug, AC ground lifter or three-prong/two-prong adapter is an adapter that allows a NEMA 5-15P grounding-type plug (three prongs) to connect to a NEMA 1-15R non-grounding receptacle (two slots).

  8. Earthing system - Wikipedia

    en.wikipedia.org/wiki/Earthing_system

    There is no 'earth wire' between the two. The fault loop impedance is higher, and unless the electrode impedance is very low indeed, a TT installation should always have an RCD (GFCI) as its first isolator. The big advantage of the TT earthing system is the reduced conducted interference from other users' connected equipment.
