add bracing to existing LV MCC
add bracing to existing LV MCC
(OP)
Does anyone have experience increasing the rating of an existing 480V MCC via installing additional bracing for on the bus (e.g. 45kA rms to 65 kA rms)?
Is this a via alternative to installing a new MCC? Any technical papers on this subject?
Thanks for your responses!

You'd also have to deal with breaker ratings, of course. If the fault current increase is not too great, a current-limiting reactor could be used.

And dpc's point about the individual bucket labeling is valid as well. If the MCC bus is braced for 45kAIC, chances are the buckets are not rated higher than that anyway.
