Refurbish and Re-use Busbar?
Refurbish and Re-use Busbar?
(OP)
I am working on a project to replace a motor control center that burned down. The client wants me to look into re-using the busbars feeding the MCC. The feeder busbars come from a sub-distribution panel nearby and enter through the top of the MCC. It doesn't look like the bars were above the main part of the fire, but I'm sure they got fairly hot. I haven't been able to locate information regarding when or how busbars can be refurbished. Anyone have experience with this?

Maybe it's just me, but I wouldn't put my name to anything using equipment coming out of that mess! What are you really going to save? Is the increased labor, effort, doubt and exposure worth a few bucks? Not in my book. If the Owner is directing you in writing to do so? That is one thing. If he is asking you to evaluate it and do so if you think it's ok? Not a chance in Hades.
And BTW, a courtroom defense that stipulates : "But all these expert yahoos on the internet said it was ok!" Doesn't wash well.
JMO,
Good luck,

480 V MCC gear is pretty close to junk even when new - it will be cheaper to buy new junk than to try to repair burned up junk.

If the bus feed was custom made, I wouldn't re-use it anyway. In the "olden days" things like that were done without a lot of design and testing. Insurance companies like to see things like UL listing now.
Waste of time in my opinion. Better off with the scrap value.
