Stacked washer and dryer already set at the final? What the NEC says about the hidden receptacle

It is a common scene on multifamily jobs: the appliance crew sets a stacked pair in a tight closet before the final, plugs it in, and the inspector has no way to put a plug-in tester on the receptacle behind it. The refrigerator outlet in the kitchen raises the same problem.

Section 210.11(C)(2) requires at least one 20-amp, 120-volt branch circuit for the laundry receptacle that 210.52(F) calls for, and that circuit may serve no other outlets, the closet light included. Mike Holt, writing in EC&M, notes that the 20-amp circuit is required even when the unit installed is a 30-amp, 240-volt combination washer-dryer.

Laundry areas are on the NEC's list of dwelling locations where receptacles need GFCI protection, and the code says the GFCI device has to be readily accessible, according to a 2024 EC&M summary of the 2023 edition. A GFCI receptacle buried behind a stacked pair does not meet that. Kitchens work the same way: under 2023 NEC 210.8(A)(6), every dwelling kitchen receptacle rated 125 through 250 volts needs GFCI protection, including the one behind the fridge, the training provider ExpertCE points out.

ExpertCE recommends a GFCI breaker in the panel, which keeps the test button within reach and lets the owner reset a trip without moving the refrigerator. In laundry closets the same breaker works, along with testing outlets before the appliances arrive or mounting them where a hand and a tester fit beside the units. Whether an inspector signs off on an outlet nobody can see is up to the local AHJ.
