Question 1

Match the outlets with the type of protection required.
-Garage receptacle outlet

Accepted Answer

Garage receptacle outlets require GFCI protection to prevent electric shock in damp environments.

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 ____.

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.
