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. Ground continuity monitor - Wikipedia

   en.wikipedia.org/wiki/Ground_continuity_monitor

   A basic summary of the cord mounted GCM involves a conductor path from the energized conductor (“hot” or black wire) directly through a low-current LED and through the ground wire. This arrangement allows an easy visible indication of acceptable ground continuity in the ground wiring (which would be indicated by the LED being on).

4. Electrical wiring in North America - Wikipedia

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

   Most GFCI receptacles allow the connection and provide GFCI protection for down-stream connected receptacles. Receptacles protected in this manner or with a GFCI circuit breaker should be labeled "GFCI protected". (Outside North America these are referred to as a "Residual-current device" or RCD.)

5. AC power plugs and sockets - Wikipedia

   en.wikipedia.org/wiki/AC_power_plugs_and_sockets

   5-20RA (Canada) or 5-20R (US) T-slot socket mounted with the earth hole up. The neutral connection is the wider T-shaped slot on the right. The NEMA 5-20 AP variant has blades perpendicular to each other. The receptacle has a T-slot for the neutral blade which accepts either 15 A parallel-blade plugs or 20 A plugs.

6. Arc-fault circuit interrupter - Wikipedia

   en.wikipedia.org/wiki/Arc-fault_circuit_interrupter

   In 2002, the NEC removed the word "receptacle", leaving "outlets", with the effect that lights and other wired-in devices such as ceiling fans within bedrooms were added to the requirement. The 2005 code made it clearer that all outlets must be protected despite discussion in the code-making panel about excluding bedroom smoke detectors from ...

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 ...
