This is my utility pole ground wire:
My service entrance has no ground.
I need to connect the ground wire from the pole directly to the service panel iron grill housing to protect it in case live wire touches it. But iron can rust even if I use a split bolt connector. How best to connect wire from grill to the pole ground? After I sandpaper the iron grill 10mm square bar portion, is there any paint that is anti-rust but conductive so the iron won't rust?
