Electrical – Circuit breaker adjustment

bedroomcircuit breakerelectricalhome-theater

Two of the guest bedrooms in my house are under the same circuit breaker trip switch. I just found out that I can't have a 1500W room heater plugged inside each of those bedrooms at the same time, as the circuit breaker trips when I do that. This is inconvenient as we use room heaters at night in the bedrooms we use to save on electric bill. Is there a way I can easily & safely "adjust" the circuit breaker so raise the "trip threshold" just enough so that it does not trip with the 2 heaters on? Or is this a job that will require rewiring the 2 rooms?

Conventional residential circuit breakers are safety devices that are not subject to adjustment. They are sized based on what the wires to the outlets can safely handle.

As you surmised, if you want to draw more power to that area, you need more wiring.
