Hello - I'm getting ready to do a heavy up and I noticed that the water pipe coming into the house is galvanized pipe to the shut off and then changes to copper pipe. I read 250.52 (A)(5)(a) and I read it as I can still use that as my grounding electrode? This is the first time I have seen any pipe other then copper. Thank you
