#12 ground wire for a spa?
I purchased a used spa from a friend. I am ready to run my electrical connections but I noticed the pig-tail that is on the spa has three 6 or 8 Gage wires for hot and common but the wire that I assume is the ground is only 12 Gage or so.
Is this because the ground wire serves only to trip the GFCI breaker (I plan to use a pre-assembled unit purchased a Lowe's or Home Depot)?
My service panel has two 50 amp breakers installed (previous spa) that I plan to use and I plan to run my wire (I will match the size on the pig-tail) through my attic and then down the side of the house, using conduit only on the side of the house.
Any thoughts on the ground wire or problems with my other plans?
