Types of GFCIs
Receptacle GFCI
Often found on construction work sites, outdoor areas and other locations where damp conditions do or could exist.
Receptacle GFCI
The receptacle GFCI fits into the standard outlet box and protects users against ground faults when an electrical product is connected to the GFCI protected outlet.
These should be tested after installation and once a month by:
- Plug in a test light or power tool and turn "On."
- Push the "Test" button on the receptacle; the "Test" button should pop up, and the power to the light or tool should be "Off."
- Push "Reset" to restore power to the outlet.
- If the above steps worked, the GFCI passed the test and is functioning properly; if the GFCI failed the test, remove it from service.
Temporary/Portable GFCI
A portable GFCI is an extension cord combined with a GFCI. It adds flexibility in using receptacles that are not protected by GFCIs.
Portable GFCI
Extension cords with GFCI protection incorporated should be used when permanent protection is unavailable.
These should be tested prior to each and every use by:
- visually inspecting the device for obvious defects and/or broken parts;
- plugging in a test light/tool to the extension cord;
- pushing the "Reset" button on the GFCI device;
- pushing the "Test" button to verify no voltage at outlet (e.g., the light or tool shuts off); and
- pushing the "Reset" button to verify the power is restored.
Circuit Breaker GFCI
The GFCI circuit breaker controls an entire circuit and is installed as a replacement for a circuit breaker on the main circuit board.
Test Light/Tool
Rather than install multiple GFCI outlets, one GFCI circuit breaker can protect the entire circuit. At sites equipped with circuit breakers, this type of GFCI might be installed in a panel box to give protection to selected circuits.
Circuit breaker GFCIs should be tested monthly. Keep in mind that the test will disconnect power to everything on the circuit.
