    Ufer ground tag, I'm not sure about this

    So I had a piece of rebar sticking out of the foundation in a garage on a house I just wired for the grounding electrode. It was coming up in a pack of studs so the framers just bent it over out of the wall. So what we did was bent it back into the wall and strapped it. We attached the #4 copper to it and put on a mudring for access. The rebar is out of the wall for about 5'' before it goes back into the wall. The garage will be finished when all said and done. I was just going to leave it up to the framers to get it all the way in the wall if the builder wanted them to. I wasn't about to cut a structural pack of studs and have a framing inspector call it. Long story short the inspector tagged me today saying that "The rebar must be in the wall in a dry location and not exposed to the elements or corrosion. He did not site a code reference. I have never heard of this. How is this different than a ufer ground in a unfinished garage? I have also done many ground clamps on rebar that has been chiseled up in the footing when the original ufer was missed by the concrete crews. I'm sure underground is a "wet location and subject to corrosion" He has passed this twice in the past. Am I missing something??

    Take a look at 250.68(C)(3) 2017 NEC

    Why is inside a garage “subject to corrosion?”. Again I wire a lot of houses with unfinished garages where the ufer is in plain view. How is this different?

    In industrial and ag buildings, I've had them stubbed up through the concrete floor under the panel. Exposed to the world forever with a ground clamp on it. It's not an issue.

    Obviously, putting something behind sheetrock doesn't magically prevent corrosion. Run a paintbrush over it or tell him it'll get sprayed with paint when they do the garage walls.

    Done. Protected from corrosion.

    Wasn't cited as a violation but inspector has asked that I put galvanized paint on a ufer. Comes in a spray can, so easy to apply and makes him happy. Works for me.

    IMO, the inspector is incorrect. There is nothing saying the rebar must be in the wall only that the connection, in this case, must be accessible. Obviously, you made it accessible with the mudring.

    Rebar is not allowed to be bent out of the footing into the earth as it will break down there but I have never heard that it would be an issue in a garage.

    If the garage was a damp location then why don't we have to use wp plates etc.
    They say I shot a man named Gray and took his wife to Italy
    She inherited a million bucks and when she died it came to me
    I can't help it if I'm lucky

    Rebar is not listed for in earth installations.

    Here is the code he sited

    300.6 (a) (3)
    Rebar outside the wall.-Ferrous metal raceways, cable armor, boxes, cable sheathing, cabinets, elbows, couplings, nipples, fittings, supports, and support hardware shall be permitted to be installed in concrete or in direct contact with the earth, or in areas subject to severe corrosive influences where made of material approved for the condition, or where provided with corrosion protection approved for the condition.

    I'm sorry, but I don't consider rebar a ferrous metal raceways, cable armor, boxes, cable sheathing, cabinets, elbows, couplings, nipples, fittings, supports, and support hardware.

    And.

    To say it can't be in contact with the dirt would be a far stretch to convince me of also.
