What can I run off a 30 amp breaker?
In a typical RV with a 30 amp electrical service some of the power hungry appliances and portable devices are the air conditioner, electric water heater, microwave, coffee maker, electric skillet, hair dryer, space heaters and a toaster.
7,200 watts
Beside this, Can I use a 30 amp breaker instead of 20?
But in general the answer is “No, do not go and put a 30 amp breaker in place of a 20 amp breaker because the wiring is most likely ‘sized’ for the 20 amp load and -may- overheat if a 30 amp load is used with wiring sized for a 20 amp load.
