Aluminum breaker bus strap

I have a 12 space 3 phase load center. Its either an old Siemans or Murray. One of the breakers burnt the tab where it clips on. I don't want to replace the whole box. The cast aluminum tab which is "L" shaped and about an inch and a half by an inch is replaceable, but no longer made. Anyone know where I can get my hands on one? The load center is 18 high by 14 and a half wide and takes murray breakers. Can post pics

Welcome to the forums.

I doubt you'll find them but a picture would definitely help us. http://www.doityourself.com/forum/el...rt-images.html

That sounds like a bus stab, but they aren't replaceable. Yes, a picture would help. Are these plug-on breakers or bolt-on breakers?

That's what happens when aluminum gets too hot, it literally burns up and disintegrates. That piece is not replaceable. IF you can get the full catalog number and IF it is a current model, you might be able to buy a new load center and swap out the interior. Those are big IFs. I suspect the best thing to do would be to replace the loadcenter.

Anything that is attached with screws is replaceable. Someone somewhere has one of these load centers that they have replaced. The aluminum burnt out because of a poor contact between the breaker and the tab it attaches to. Unfortunately I dont have any numbers. Im definitely not replacing the whole load center. Its way too much work.

A lot of bigger cities have electrical supply recycle scrap dealers who have a bunch of old junk you can dig through to find replacement parts. Might be listed in the yellow pages or you might be able to find one by calling around to local supply houses and asking if there's a dealer of used electrical equipment nearby. Failing that maybe try eBay?

Tried ebay but didn't find anything. Thanks for the tips. I'll definitely look into the recycle scrap dealers.
