man, what kind of circuit setup do you all have that adding one server trips three breakers... yikes. Well, at least that shouldn't be your fault, should be a power-guy that is responsible for signing off on that stuff. That doesn't help the fact that you had to bring all those downed boxes back online asap and screw up whatever other plans you had for that day...
Company must be going through some serious growing pains and not willing to spend extra on IT--at least that's my guess.
