We will be improving/replacing our electrical service's earth ground, currently a galvanized pipe in the ground with a maybe 10 gauge copper conductor leading to 1970ish split bus Square D electrical panel.
New grounding will be three 5/8" x 8' copper-clad grounding rods, set 6' apart with 4 gauge copper conductor running by each and to electrical panel. Our city electrical guide implies that antioxidant paste must be used not just with aluminum, but with all connections including copper/stainless wire mechanical connections or even split bolts.
Should I use the copper antioxidant paste I have (Kopr Shield) at each 4 gauge wire/grounding rod acorn connection? How about on the 4 gauge to electrical box screw connection?
