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. NEMA connector - Wikipedia

   en.wikipedia.org/wiki/NEMA_connector

   In addition, a tripped GFCI receptacle may be more easily noticed and reset, as compared to a tripped GFCI located in a remote circuit breaker panel far from the point of usage. Like most current interrupting devices, a GFCI receptacle can optionally be wired to feed additional "downstream" outlets; correctly installing one GFCI receptacle in a ...

4. Three-prong adaptor - Wikipedia

   en.wikipedia.org/wiki/Three-prong_adaptor

   Replacing the obsolete receptacle with a GFCI receptacle is the safest alternative, other than installing a new cable from the main circuit breaker panel. If a Ground Fault Circuit Interrupter receptacle is properly functioning, it will interrupt dangerous current to limit the duration of a potentially lethal electric shock from an appliance ...

5. Ground (electricity) - Wikipedia

   en.wikipedia.org/wiki/Ground_(electricity)

   A ground fault protection relay must trip the breaker to protect the circuit before overheating of the resistor occurs. High-resistance grounding (HRG) systems use an NGR to limit the fault current to 25 A or less. They have a continuous rating, and are designed to operate with a single-ground fault.

6. 10 Safety Tips for Hanging Christmas Lights Like a Pro - AOL

   Additionally, it's a good idea to plug the Christmas lights into a ground-fault circuit interrupter (GFCI) outlet which will automatically shut off power to the lights if it detects electricity ...

7. Electrical wiring in North America - Wikipedia

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

   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 ...

8. Never Plug These 12 Things Into Your Power Strip - AOL

   www.aol.com/finance/never-plug-12-things-power...

   Electricity and water don’t mix, and power strips are especially vulnerable to moisture. A sump pump should always be plugged into a GFCI (Ground Fault Circuit Interrupter) outlet. This type of ...

9. Ground continuity monitor - Wikipedia

   en.wikipedia.org/wiki/Ground_continuity_monitor

   The automatic cord mounted GCMs eliminate the need to test each cord or circuit, since the electrical impedance to ground is measured at the attached cord device and visibility indicated there via an LED. These inspections are required by the OSHA regulation on “receptacles which are not a part of the permanent wiring of the building”. [3]
