A contractor is installing GFCI protection for a bathroom renovation. Which of the following locations requires GFCI protection according to electrical code requirements in Michigan?
Correct Answer
D) All bathroom outlets within 6 feet of water sources
GFCI protection is required for all outlets within 6 feet of water sources in bathrooms, including sinks, tubs, and showers.
Why This Is the Correct Answer
NEC 210.8(A)(1), adopted by Michigan, requires GFCI protection for all 15- and 20-amp, 125-volt outlets in bathrooms. The practical interpretation applied in Michigan is that all receptacle outlets within 6 feet of a water source (sink, tub, shower) must have GFCI protection. This distance-based rule captures the hazardous zone where water contact with electrical outlets is plausible.
Why the Other Options Are Wrong
Option A: All bathroom outlets and lighting circuits
Lighting circuits in bathrooms are not required to have GFCI protection under NEC 210.8 — only receptacle outlets (plug-in type) require GFCI in bathrooms. Including lighting circuits is an overstatement of the requirement.
Option B: Only outlets within 3 feet of the bathtub
Limiting GFCI protection to outlets within 3 feet of the bathtub is too restrictive and does not match any current NEC provision. The 6-foot radius from water sources is the standard; a 3-foot limit would leave many potentially hazardous outlet locations unprotected.
Option C: Bathroom lighting circuits only
Bathroom lighting circuits only is incorrect in two ways: (1) lighting circuits are not the NEC requirement — receptacle outlets are, and (2) protecting only lighting while ignoring receptacles near water would miss the primary shock hazard locations in a bathroom.
Memory Technique
The GFCI rule for bathrooms: 'All receptacle outlets, 6 feet from any water source.' Picture a 6-foot radius circle drawn around every sink, tub, and shower drain — any outlet inside that circle needs GFCI. Lighting overhead does not count unless it has a plug.
