Re: Main breaker tripping, dead CIM

We were running a compressor for all of Chesapeake, which certainly would increase our current draw by a lot. We do not really wish to go back to not having a compressor, though - we were that way at DC because our ball-acquisition was non-functional.

Our drive efficiency is, as far as I can tell, quite good; there's not too much friction in the KOP belt setup. Our wires are all way longer than they should be, though, and it's not particularly feasible to fix the wiring at this point in time.
