My friend had told me that a room only uses 1200W at a time, so I'd have to get a wire connecting to another room if i was to plug in anything else?? Sounds ridiculous to me, but i couldn't find anything about it online.
Most rooms have one or two 15-amp or 20-amp circuits though some older ones may be only 10-amp. One 15-amp circuit can handle about 1800w. If you have access to your circuit breaker, it should be listed there.
