They use CCA wire for transformers, and don't even solder the connections inside anymore. It's just a wrap with some solder on the connecting wire to stiffen it - but solder doesn't stick to aluminum so there's no electrical or mechanical connection other than the tape on the transformer. It literally just pulls right off.

Yeah these blow out all the time Whenever a building does "scheduled power maintenance" I figured out if I don't unplug all the ups, they will blow out

Which sucks, because APC used to be the top-tier in UPS equipment. I still have a bunch of those old back-ups running stuff here.
