-Garage receptacle outlet
A)GFCI
B)AFCI

Question 2

When an existing two-wire, nongrounding-type receptacle is replaced in a location where the Code requires a GFCI receptacle, it is permitted to be replaced by a ____.
A) GFCI receptacle
B) two-wire, nongrounding-type receptacle
C) three-wire, grounding-type receptacle
D) all of these

Accepted Answer

When replacing an existing two-wire, nongrounding-type receptacle, the Code requires a GFCI receptacle to be installed to provide ground-fault protection. It is not permissible to simply replace it with a two-wire, nongrounding-type receptacle or a three-wire, grounding-type receptacle without running a grounding conductor to the receptacle. The use of a GFCI receptacle in this instance allows for ground-fault protection without needing a grounding conductor.

Accepted Answer

GFCI (Ground Fault Circuit Interrupter) protection is required for kitchen countertop receptacles, bathroom receptacles, and receptacles in crawl spaces at or below grade to protect against electrical shock. However, a built-in dishwasher is not required to have GFCI protection, as it is considered a fixed appliance and the requirements for GFCI protection typically apply to outlets where there is a higher risk of electrical shock due to the presence of water or damp conditions.
