Space Heaters and Microwave Cause 30 Amp Circuit Breaker to Blow on Travel Trailer

Question:

When I run two space heaters and put something in the microwave, it blows my 30 amp breaker. Was considering,a 40 amp breaker. Would that be unsafe?

Space heaters and microwaves, depending on the sizes of each, can draw a lot of power and I could see how it could blow a 30 amp circuit breaker. To handle a higher power draw you could try a higher capacity breaker as long as everything else in the system such as the wiring and any switches are also rated as high.

I recommend checking the information on each of the heaters and microwave to determine what the combined amperage draw is if all were running at peak draw at the same time. It may end up being a situation where you would have to turn off the heater(s) before using the microwave.
