The few residential hot tubs I have wired I used a spa disconnect which has the GFCI breaker inside it. I installed it futher than 5ft but within site of the tub. After looking at 680.41 I am a bit confused. It says this requirement shall not apply to single family dwellings???? Does this mean the GFCI breaker could go in the main panel and pipe right out to the tub? Maybe a emergency switch for Spa's and Hot Tubs is somthing different???
