I hired a contractor to wire my outdoor hot tub and I'm not sure he followed the code. He installed a GFI breaker in the main box, ran the wire outside to a disconnect box near the tub. The disconnect box can easily be reached while in the tub. I thought it had to be at least 5 feet away, but the contractor said that the disconnect box also contains a GFI, and it can be within 5 feet of the tub. Does anyone know anything about the NEC and whether or not I am OK by code?
