Either keep mom's vacuum cleaner off your circuit and you should be good.

Okay, well how do I know which room is part of which circuit? And how much can each circuit take? I'm guessing around 2000w because that's what my computers were drawing.
Your average 15Amp 120 volt receptacle will spit out 1,800 watts maximum. It is only recommended to operate at 80% continuous load however, or 1,440.
I hope you are paying your parents at least $50/month for using so much electricity!
