I am installing a hot tub in my back yard. Hot tub sits on 3- 6 x 6 wood beams which themselves sit on a concrete aggregate pad. We built a deck around the hot tub. We are wiring
the hot tub with #6 thhn wire. We have 4- 100 foot lengths of this wire...black, red, green and white. We wired the black and red to a 60amp breaker (non gfci) from the house panel in the garage, out the wall to the outside of the garage which is in a junction box
and then into 1.5'' schedule 40 above/below ground pvc. The wires in the house panel are one black and one red to the breaker, the white and green go to the same bus bar. The conduit
goes under the drive way and stretches 50 feet into my back yard.
From there the wires currently come out of the ground and stretch another 40 feet through the grass to the hot tub. We just connected the wires to see if the tub works and it does.
My plan from there is to come up out of the ground and reduce the conduit from 1.5'' down to 1'' and then go up along a 4x4 post through the bottom of the deck into our spa disconnect panel. In the panel we have a 60amp gfci breaker. There we will wire the white and green to separate bus bars that are labeled for white and green inside the disconnect panel. The red and black will go to the gfci breaker.
What I want to do from there is come back out of the spa panel in 1'' conduit, through the deck floor and then stay in 1'' conduit and mount the conduit to the bottom side of the deck. This run would be 30 feet to the hot tub where the 1'' conduit would connect to flexible conduit and the flexible conduit would connect to the spa electric panel.
My questions: Does it seem correct what we've done so far? And is it legal or code to not bury the conduit that runs under the deck but rather attach it with brackets to the bottom side of the deck? I intend to call an electrician friend of mine when he's back from vacation to come out and look everything over but I want to get it as correct as possible both for safety and because he will bust my chops if it's not right.
