Installation details [RE-wrenches]

[Tom Simko]

    Since when is concrete conductive? Photo 6 in the below installation
detail shows a footer with a ground wire being filled with concrete. While
I'm NOT an electrician, I have been in construction all my life (so far),
and was always under the impression bare copper and concrete is a bad
combination, something about the calcium chlorate in the concrete eats the
copper. I do know that any slab with copper water supply lines coming up
through it must have a buffer of some sort, usually a piece of Rubetex or
some other pipe insulation. By coincidence I just poured a footing 2 days
ago, and the electrician had ran his ground (residential on grid residential
addition, no alternative energy involved) down my horizontal rebar in the
footing, where it would have wound up encapsulated in the concrete. I
unwound it from the rebar and laid it in the dirt along the footing form,
and later backfilled over it, and mentioned doing so to the Sparky. He said
the inspector told him to do it that way. Huh? What am I missing here? I'll
be seeing the electrician tomorrow, back me up here or tell me where I'm
wrong!
