I am currently wiring for a spa. Have dug an 18 in trench. I will run (4) #6 wires to a 60 amp breaker box approx 55ft away from the main panel and then run from that box the additional wiring 25ft to the hookup spot for the spa 8ft x 12ft (which will be hard wired. Have a few questions: One, is 1 inch schedule 80 conduit enough room to run the 4 lines of #6 wires?
And two, what changes to the spa wiring could I make if I wanted to convert that area with a small guest home (tuff shed 10 x 20) in the future? The shed would be a small tiny home with bed, small electric stove, some electric outlets for TV, fan, small AC in a window.
This spa project is in Tucson, Az and want to i stall a Tidal Fit Spa 8ft x 12ft panel says 50/60amps. I talked directly to the guys at the spa and they stated not to step down the ground to #8 (as I wanted to do that). The spas is suppose to have (4) #6 wires. The inspector may not pass it. I have been waiting during this time over 20 days just to get a case number to then request an inspector. (See attached diagram).
The spa wiring I feel good about. The part I was hoping to learn about is how can I convert this wiring later on should I add a small room with lights, a few outs and maybe a hook ups for a small electric range and mini fridge. What I am hearing is I could/should add another smaller sub panel.
I AM NOT an electrician just trying to learn from the pros.
