PING: Walking NEC wizards sub: Panel Ground wire

ok, after putting on a #4 ground to the outside rods AND to the plumbing
inside, my local city inspector says the wire has to be in conduit anywhere
it's in close contact with concrete. I totally missed this in the code.
Can someone cite this for me? The reason i went with the #4 is because the
book said it didnt' need conduit for physical protection. I never saw any
mention of concrete or electrolisys.

thanks
