underground electrical conduit
I need to run 30' 12" deep PVC conduit for a hot tub. Using 3 #6 and 1 #10 for ground. #6 is THHN. I was told the bend coming up from the ground need to be galvanized. The end up to the LB going into the house and the end to the GFCI cutoff. Both the bend 90 and the pipe up should be metal. Anyone heard of this before ??
