So the ice storm the othe day took down many trees in our area. My BIL called me because a branch fell and knocked his neutral wire loose from the weatherhead. Some things worked others didn't, biggest problem was when the fridge kicked on the whole house went dim.
I asked him about a ground rod and he was sure he didn't have one. Until he could get a guy to climb up there I told him to go get a ground rod at the Borg and pound it in as far as he could and connect it to the ground/neutral bar in his panel. He was able to get the ground rod about 5' down with a hammer and connected two 12ga copper wires from the rod to his panel. After he did this there was no improvement at all.
An hour later an electrician he knows showed up and reconnected the neutral to the weaterhead and all was better. Neither of his hot leads at the weatherhead were loose or needed to be touched. So why wouldn't going directly to ground from the panel have helped his problem?
