Is It OK To Run My RVs Air Conditioner When Plugged Into House Electricity?
Run Your RV’s Air Conditioner When Plugged Into House Electricity
I just purchased my first RV, an '06 Jamboree class C; the dealer said not to run the AC off an extension cord from the house but to only run it off of the generator. Why would this be necessary? I accidentally ran it once, and it seemed to work okay. Will this cause any damage? Thanks.
ANSWER First, you have probably not caused any damage to your RV's Air Conditioner. You can safely run one RV Air Conditioner off of a 15- or 20-amp house electrical receptacle as long as you follow the instructions below:
1. First, determine if the electrical outlet you are plugging into is 15 or 20 amps. If you look at the circuit breaker for that circuit, you will see the amperage marked on it. A 20-amp circuit will give you a little extra leeway as far as what else you can run in the RV when the AC is on. Make sure that nothing else is plugged into the circuit you are using.
3. The ideal situation would be for your RV's 30 amp power cord with the adapter on it being long enough to reach the outlet on the house. But if it does not, you are going to need a 25' 10 Gauge Extension Cord. You just cannot use any old extension cord. If the extension cord is not a heavy enough gauge it can overheat and cause a fire or prevent the proper amount of voltage or amps from reaching your RV, which can damage the AC. This is probably what the dealer was referring to.
Our RV has 50 amp service, but when our RV is at home we use a 50 Amp To 30 Amp Adaptor and use the 30 Amp To 15 Amp 125 Volt Adapter to plug into our house. The house receptacle I plug into is only 15 amps, but has no other items plugged into it. Even with this connection I am able to run one of the roof Air Conditioners and still use the TV.
Now I cannot run the Air Conditioner and the microwave at the same time as it kicks off the circuit breaker in the house. This would also be true with running the AC while running a toaster or a hairdryer, etc. You cannot run a lot of high amp demand items at the same time when hooked up to a 15 or 20 amp system. But if you follow the steps outlined above, you should be fine.
The Ultimate Solution to Plug Your RV Into Your House
The best solution to safely plug your RV into your home electric and be able to run all the electrical accessories in your RV is to have an electrician install a RV Electrical Panel.
CAUTION Before calling the electrician, watch the short video below to learn what the electrician needs to know when setting up the RV Electrical Panel.
