I am trying to complete the electrical wiring for a hot tub to be installed on an outdoor deck. I have a dual pole 50A circuit breaker in the breaker box and indoor 6/3 wire. The total distance from the box to the spa will be about 100 ft. 75 ft indoors and the last 25ft I'll run in conduit outside. So what's the problem? I'm having trouble finding/installing the right Disconnect. The closest thing I can find (@ Home Depot) is a 60 Amp Disconnect for an Air Conditioner. I'm told this should be fine, since the disconnect is there for safety and the 50A breaker in box will trip if necessary. I bought a Cutler-Hammer 60A Two Pole A/C Disconnect. However, upon getting it home and taking a closer look...it would appear that this disconnect is for 2 conductor wire, not 3. So I guess I have two questions: 1 - Does someone make a Disconnect specifically for a Hot tub? and where can I find/order one? 2 - Failing #1 will the A/C disconnect work and what is the right one to look for? Thank you

I wired 2 outside free-standing lamps, what size of switch do I need (15/20amp)? I wired my first 3-way switch and the light seems to work properly, can I assume it is wired correctly? Could an improperly wired switch or outlet in an electrical box cause a fire or would the circuit breaker blow first?
