But the secret power story reminds me of the time I rearranged the circuits i a breaker panel because somebody was always switching off my wall clock when they switched off the lights. So after the change they were switching off the local air conditioning, which eventually caused them to be more selective in the circuits they switched off. Some folks, those who ignore signs, sometimes do learn eenually.
But moving circuits has served well on several instances.
I'll take the heat for being the voice of safety first... This sounds like he jumped around what was most likely a locked out/tagged out circuit. I know he knew what he was doing but it was still a no-no and possible illegal. As in if someone got hurt in another part of the building oops would not have been accepted.
Circuits are sometimes not as clear cut as one breaker, one office. We have had partitions and even walls moved over the years, the circuitry has not always been modified to match, especially the lighting circuits.
I know I'd be in deep doodoo if I tried this without consulting building management and the maintenance department.
The short version of my point is that this is a "Do not try this at home" moment.
At New Mexico Tech in the late 70's, we had a DEC 20 with TOPS-20. The load average (a quaint term...) was terrible 8am to 11pm. So, the CS guys (ie me and others) would show up at 11pm to work all night. At 8am, the load average woould do a step function from 1 to 25..30 - a log scale IIRC.
Pizza was out - there were two places in town and they closed at 10. Besides, we were poor enough. Many a night with Dr Pepper, Ritz Crackers, and Velveeta. Yum.
The CS instructors never started a class before 11am to give us time for breakfast, shower, and a morning class.
