Currently I have two 15amp breakers that trip quite often. Scenario 1: Heating element in ceiling of bathroom is on, wife uses hair dryer - breaker trips. In my panel this is circuit #16 with a 15amp breaker. Scenario 2: Electric oil heater on in living room, multiple room lighting and sockets are on the same circuit - this is circuit #24 with a 15amp breaker. Upgrade plans: Install 30amp breaker in place of 15amp, is it safe? I would assume splitting out the load to new wiring would be the recommended approach and there is plenty of space in the panel for that. However, I'm just not up for making new runs at this time within the house. I'm pretty sure the wiring in place is 10awg but I'll have to check.
