Is GFCI Protection Required in a Residential Garage?

Short answer for the user who asked the app this week: yes. NEC 2023 210.8(A)(2) requires GFCI protection for all 125 volt through 250 volt receptacles installed in a dwelling unit garage, and also in accessory buildings with a floor at or below grade that are used for storage or work areas.

No more exceptions

Veterans remember the old carve outs: the single receptacle for a cord and plug appliance like a freezer, and the receptacle that was not readily accessible, like the ceiling outlet for the garage door opener. Both exceptions were deleted back in the 2008 cycle. Every garage receptacle since then needs GFCI protection, including the freezer circuit, the opener receptacle in the ceiling, and any dedicated circuit for a shop tool or a second refrigerator.

The 250 volt expansion

Notice the current language says 125 volt through 250 volt receptacles. That wording, which arrived in the 2020 cycle, pulls 240 volt receptacles into the requirement. A 240 volt welder receptacle, a compressor circuit, or a Level 2 EV charging receptacle in the garage all require GFCI protection under the 2023 code. For EV charging specifically, 625.54 confirms GFCI for the receptacle installations. Hardwired EVSE units follow their own rules, which is one reason many electricians prefer hardwiring the charger.

How to provide it

Either a GFCI breaker in the panel or a GFCI receptacle device works. For a string of garage receptacles on one circuit, a single GFCI receptacle at the first outlet protecting the downstream outlets through its load terminals is the economical route. Mark the protected downstream receptacles with the GFCI Protected labels that come in the box, per 110.3(B) and the device instructions. For 240 volt circuits you will be using a two pole GFCI breaker.

Nuisance trip reality

Freezer on a GFCI is the classic callback fear. Modern GFCIs are far better than the 1990s units, and a tripping GFCI on a freezer circuit usually means real leakage current in the appliance or its cord. Chasing the leak beats removing the protection, which is now a violation with no exception to hide behind.
