On a related note, did you ever get into the 277 when you were looking for 120?
We had that happen in my office building once. The "building electrician" (aka janitor with a screwdriver) hooked up a 5-15 for a new computer and took it from the lights.
Fortunately the only thing that blew was the monitor. The power supply in the system unit was autoswitching and survived until the breaker popped on the power strip.
The monitor was spectacular tho. You could see scorch marks out of every little slot in the case. The girl who plugged it in said it looked like one of those air bursts on the 4th of July. It was a good thing she turned it on from the strip so she wasn't really close.
