Hello All,
Frequent reader, first time poster. I see this has been discussed before to some degree but cannot find an answer.
Just did an install with a Cooper B-Line CT cabinet with 500 MCM cable which the local utility company required for 400AMP service.
For a neat install decided to go out of the cabinet from the back to feed panel board directly behind it.
Utility company inspector came out and is concerned with wrinkles in the 500 mcm cable outer jacket. I haven't even landed on the lugs yet and there is a slight radius to the wire simply from pulling it into the CT cabinet which caused the wrinkles. The inspector is suggesting replacement of wire! When I land to the lugs I am going to have to put a tight bend/ loop.
Is it possible to bend 500 MCM cable without wrinkles to the outer jacket? If so, how do you guys do it? I'm looking at Greenlee Wire Bender but don't see how I can bend the wire without some wrinkles even with that.
I really don't want to have to replace the 500 MCM cable is it industry practice to install 500 MCM without any wrinkles in the outer jacket when you have to make a 90 degree bend or loop or even worse go through an LB?
I am only talking about the thin outer jacket with the cable identification and listings printed on it.
Thanks!
