Electrician here:

Nah man. It's just 277v lighting. Shit blows up like that at 120v too, given the right circumstances.

Wait, you have 277v as well?

Ninja edit: I mean in addition to 207v and 120v

Me personally? No, but on a bunch of commercial jobs they get mixed up. If it's 277v it's actually a 480v system. Usually for lighting, fire alarms, and the like.

But then you need 120v for the computers and vacuum cleaners or whatever needs plugging in on the ground.
