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.
How many outlets can you run on a 30 amp breaker?
The NEC states that you can only have 30-amp receptacles on a 30-amp circuit. If its a multi-outlet circuit, you can have a 20-amp breaker protecting the #10 conductors and use 15amp and 20amp receptacles on the circuit.
What size breaker do I need for a 30 amp generator?
A 30-Amp Double Circuit Breaker has two breakers, each rated at 30-amps, tied together so if one trips, they both trip. The wire size for a 30 Amp 240 volt circuit is 10-gauge or larger because each wire and each circuit breaker may carry up to 30 amps. 50 Amp 240 Volt Wire Size is 6-gauge or larger.
