I wired my house for a hot tub using 8-3 w/ground UF wire (from a 60 amp GCFI sub-panel to a 4hp hot tub motor). The inspector told me even if I have the UF wire in a conduit I have to bury it 12 inches. I bought PVC conduit pipe - it can be on top of the ground so why does it have to be buried? What does the NEC state as the requirement for the 8-3 UF wire from the sub-panel to the tub?

Direct burial cables (Type UF for example), must be buried 24" and non-metallic raceways (PVC) must be buried at least 18".

Your inspector is letting you off easy, your cable is too small for the breaker you are using. #8 cables should only be protected at 50 amps.

I agree with Tom O,

one would not wish to be planting a shrub years from now and encounter said 8-3 wire..


also there is a minor code issue with UF feeding outdoors to a hot tub.
