How many amps does an AC breaker draw?
Most common voltage ratings for AC units are 115, 125 and 220 volts, and amperage rating can run from 15 to 20 amps. The lower two voltage ratings are common in smaller units, while units with a rating higher than 15,000 BTUs will require a 220-volt circuit.
Why does my RV AC trip the breaker?
It can be very frustrating when your RV air conditioner constantly trips the breaker on a hot day. This could be caused by several reasons. You’re running too many high-powered AC (alternating current) appliances The rooftop air conditioner draws a lot of power, potentially putting your electrical system right on the edge.
When do you know you need an RV breaker?
If an RV breaker trips, you’ll generally know it because the power to whatever you were using will simply stop. For one of our recent acquaintances, a European couple traveling through the states in a rented motorhome, a long, hot summer night without air conditioning signaled their problem. We were able to help them with the fix.
Why are breakers tripping when using a / C?
We have an electrical readout on the dash of our motor home and one of the first things I check when we are running air conditioners is the voltage when both air conditioners are on. Another possibility is that the breaker itself may be defective.
How does a voltage interrupter work in a RV?
Let’s take a short look into the world of these voltage interrupters. Your RV “shore power” system is somewhat similar to your stix-and-brix cousin’s. Electrical power flows into the rig through a distribution panel. Once at the panel, the power flows to various shore power circuits through circuit breakers.

Is the Dometic rooftop AC throwing breaker too hot?
The compressor in the rooftop unit is way too hot to touch. I have replaced the circuit breaker (it was tripping at 13.5 Amps on a 15 amp circuit.) After letting everything cool off for a couple hours (still in 100 degree afternoon heat) I put a clamp on amp meter on the feed wire and turned on the A/C.
Do you need a circuit breaker for an air conditioner?
Again, in the case of air conditioners, we don’t need to match up the size of the circuit breaker to the wire sizes. To paraphrase from EIOED, this is because air conditioner compressors contain thermal cutouts designed to help prevent damage to the units, and these would open before it became a problem for the wires.
