Show answer & explanationAnswer & explanation
Correct answer: C. GFCI protection is required for all 120-volt, 15- and 20-ampere receptacles in commercial kitchens.
According to NEC 210.8(B)(2) as adopted by the CEC, all 125-volt, single-phase, 15- and 20-ampere receptacles installed in commercial and industrial kitchens must have ground-fault circuit-interrupter protection.
Why the other options are wrong
- A. The NEC does not provide an exception for specific appliances in commercial kitchens regarding GFCI requirements for 15- and 20-ampere receptacles.
- B. GFCI protection in commercial kitchens applies to all 125-volt, 15- and 20-ampere receptacles, not just those serving countertop surfaces.
- D. The 6-foot rule applies to dwelling unit kitchens, not commercial kitchens, where the rule is more comprehensive.
