? regarding service entrance grounding electrodes
#15
Jerry,
It skins the surface; Really? Whoa, now that is an impressive insulator! I’ve never seen that over there before and have never heard about it on the ground but it’s on par with trees, I’ve seen the effects of skinning around our large evergreen trees here with wide spiraling deep burn marks around the trees trunks. That's BIG TIME bad news about the Lava though. Yeah - that would be confirmation of my suspicions. That’s all the more reason to get a huge conductive cocktail slab in place. In bare lava there's certainly a need for something to absorb a lightening charge in a capacitive manner and a properly doped driveway pad could certainly do the trick. That’s some mega amperes indeed and a big time potential killer. I’m going to dig into this issue more deeply.
Edit to add;
IEEE-142
E ho'a'o no i pau kuhihewa.
