Cusser Posted December 14, 2020 Report Share Posted December 14, 2020 I bought my CalSpa Hawaiian model in 1988, brand new. We had a qualified electrician; he added a 40-amp dual circuit breaker, ran 240 VAC lines through the attic and through conduit down to the spa and connected it. Like many, we knew absolutely nothing about spas. Anyway, the spa did have a GFCI for the spa light ONLY. Maybe that was OK with code then, I didn't give it a second thought until I read about such GFCI in Popular Mechanics magazine, so I bought a 40-amp GFCI breaker, box, etc., and wired that into the main 240 volt power feed, inside the redwood cabinet. Yes, we were likely in real potential danger until then. So question for you electricians - when was GFCI made a requirement for the entire unit, heater, pump, etc ?

Before that they did not make gfci breakers, and to get protection for the whole spa required a different type of dead front gfci with a loop on the back. 1 Quote Link to comment Share on other sites More sharing options...
