I had a 125 amp sub panel installed in a small water heater room (with a door to the out side) when I had my house built a year ago. I am now ready to install the spa. The subpanel was designed for a spa and has a 50 amp GFCI 220 volt breaker ready to go. My question is how do I run the electric to the spa area, about 15'. It will need to run through the wall to the outside and then 10' to the patio where the spa is located. I have purchased 20' of 6/3 wire and a Breakerless shut off that will need to be installed. What type of conduit do I run from the Sub Panel to the spa connection? It will be exposed on the outside of the house.
