So all of the UPS boxes in my office were firing randomly all night. Plugging a voltmeter into the outlet revealed consistent drops under 112 VAC every minute or two so I called Mass Electric to report the problem. After blaming my internal wiring the incredibly chipper CSR agreed to dispatch a tech. A few minutes later, a Mass Electric service van rolled up, he plugged a voltmeter into my box, said “235 VAC/118 VAC, perfectly within spec” and left. He couldn’t have had the meter plugged in for more than three seconds. When I stopped him and said that we had well over a hundred brownouts, he said he’d “let them know” and drove off.
Bastards. The lot of them.
