Code Q&A: GFCI Protection Requirements in a Dwelling Unit Garage

April 9, 2015

NEC guidelines for GFCI protection in a dwelling unit garage for a dedicated receptacle for a fixed appliance

Q. Is GFCI protection required in a dwelling unit garage for a dedicated receptacle for a fixed appliance like a freezer or in the ceiling for a garage door opener?

Find the Answer

A. GFCI protection is required for all 15A and 20A, 125V receptacles in garages, and in grade-level portions of accessory buildings used for storage or work areas of a dwelling unit [210.8(A)(2)], as shown in Fig. 1.

Although a receptacle outlet is required in a dwelling unit attached garage [210.52(G)(1)], a receptacle outlet isn’t required in an accessory building or a detached garage without power. However, if a 15A or 20A, 125V receptacle is installed in an accessory building, it must be GFCI protected [210.8(A)(2)], as shown in Fig. 2.
