    And.

    Agreed


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

    It is in the listing of the rebar. Rebar will rust and many inspectors will turn it down if the cee is connected to it underground. Why is that hard to believe. Check with some building inspectors- go on some engineering sites to check it out. Of course, you don't have to believe them either.

    She inherited a million bucks and when she died it came to me
    I can't help it if I'm lucky

    I can see the rebar rusting, but, a lot would have to happen for the rebar to actually "break down there".

    I agree it might eventually rust in half, but probably not in my lifetime.

    Oh well, the rebar thing would not be my first choice for a CEE anyway.

    I did not fully read the post and thought that the rebar was bent outside of the building and then bent back inside the wall leaving part of the rebar exposed to the elements. My mistake. The code article that I posted does not apply to the original post.

    It depends on the type of soil. I have read from 1 year to 10 years but I don't know. Ground rods rust also and have a lifespan of 20-30 years depending whether it is galvanized or copper.

    I'm with ya on that.

    I had a 15' piece of 3/4" rigid run from my house to feed my garage when I first moved in thinking it would last forever.

    After about 10 years I dug down to pour concrete and found that there was nothing more than the wire left in the dirt.

    The pipe had completely disintegrated around it.

    Thanks for the information. I never knew until know the rebar wasn't to come in contact with the earth.
