rated 150 volts to ground or less, 50 amperes or less and three-phase
receptacles rated 150 volts to ground or less,
100 amperes or less installed in the following locations shall
have ground-fault circuit-interrupter protection for personnel.
(1) Bathrooms
(2) Kitchens
(3) Rooftops
Exception: Receptacles on rooftops shall not be required to be readily
accessible other than from the rooftop.
