Did I break it

That’s interesting (well, to me anyway!) I’ve wondered about older appliances that were labeled as 110 or 115 volt and didn’t realize there had been an upward push of the rms ac house hold current. I’ve only recently discovered 277/480 volt single phase systems and imagine the older 440 and 460 single and three phase systems were also a part of that change.

Yeah the higher the voltage, the less the current so they can get by with smaller cables and wires. Saves on copper for sure. In some of our substations we had voltage regulators which would automatically change the # of windings they would pick up. This was to adjust for voltage sags or when it may have gotten too high.
