Im unclear as to what i need for my bathroom circuit. the code reads. ground-fault protection shall be provided for all 125-volt, 15 and 20 amp receptacle outlets installed in bathrooms. also a hydro-massage bathtuds (with a recirculating piping system, designed to discharge water upon each use.) shall be supplied by an indivdual branch circuit with gfci protection. My questions are do i need the protection at the receptacle or at the breaker? And does this code apply to a airtub it does not recirculate water?
