I am installing a used hot tub that requires a 50 amp circuit. I have run 6/3 w ground cable to the disconnect (about 30'). My question is about what is required for the ground between the disconnect and the hot tub. The hot tub equipment is bonded by a #8 solid bare wire to the ground lug on the controller box of the hot tub (by the original owner).
The run between the GFCI/disconnect and the hot tub spa pack is about 13'. (The disconnect is in sight and located ~6' from hot tub.) I plan on running 8' Schedule 80 3/4" conduit then 5' non-metallic water-tight into hot tub. (1" water-tight is too big to pass through the channel built into the fram of the hot tub.) I know that I am running #6 stranded THWN non-grounded conductors for the two hots and neutral.
What do I need to run for a ground wire? Size? Insulated/non-insulated? Solid or Stranded?
Thanks for your help!
