    Guys,

    I am looking at needing to cut and add a sweep to some underground conduit, as the arrangement of the service has changed.

    This was installed 40-50 years ago. The crud is down 5' in a hole and is tough to get at.

    What sucks: it looks like 2 1/2" abs. It certainly is All Black Stuff. But no such size exists.

    It really is down pretty far. Any deeper and I could drop a casket in there. So I am having difficulty working out exactly what it is.

    So I wonder, is it in any practical way possible to join ABS to grey pvc? That I can get in 2 1/2", including a sweep.

    I wonder if I need to just use a rubber coupling?

    Or have I got it all wrong, and the stuff is actually 2"? I would not put it past the local utility...

    Not sure but that sounds like it could be a Gas line.

    I would check it before I started cutting.

    No, no. The gas comes in quite elsewhere.

    The general had a utility spotter mark things.

    Got it worked thru today. Believe it or not: two #2 and one #4 aluminum, in 1 1/2" abs.

    And we are replacing the 100 panel with a 200 amp panel. It has been approved. I don't get it.

    the answer lies in the utility rules not the NEC.

    THere should be a lot of difference in the "looks" between 2 1/2" and 1 1/2" conduit.

    Hi Don. Eating too many bean burritos makes everything sound like a gas problem:cool:

    Yeah, it was 5' down in a pit. Hard as hell to work on in any way.
