In a residentual single family dwelling with a (whirlpool/shower/steamroom) enclosure,this is a single combination use module. The whirlpool portion is supplyed by 2 20amp GFCI circuits (both circuits controlled by dead front GFCI devices located near the tub inclosure, the load side being terminated in single 20 amp recepticals to be cord connected to each the pump and inline heater).The steam generator is located in the basement 15 feet from the main service panel (within direct site), this is a 2 pole 20 amp circuit. The steam generator has a built in GFCI control (first one i've ever seen). The question is...Is it permissible to install merely a breaker Lock or would one need to adhear to the code more rigidly and install a disconnecting means(other than the breaker itself)?
