Plugging in at home

[JNKS2010]

my wife and I are fairly new to TT camping. we have an adapter that we put on our 30 amp power cord that allows us to plug in at home to our garage outlet. that allows us to get power to pretty much use everything. we open the slide, run the fridge open close the cannopy. however, it seems our dometic ac will not run while plug in at home. is this normal? or do we have an issue? I would appreciate any and all feed back. thanks in advance.

Most likely your home plug is 15amp or at best 20amp.. the load is just too much for the circuit with the other stuff like the converter, fridge, TV etc.. especially if you use an extension cord. What you need to do is have an electrician come wire you a 30amp or even a 50amp plug so you can connect and run everything.

Just remember an RV 30amp plug isn't wired the same as a 30amp dryer plug

If you are plugged into your house (15A circuit??), you usually will not be able to run your A/C in your RV. Don't forget that the A/C is not the only item drawing current in your RV. The converter requires several amps as well as any hard wired sensors. If you have your HW heater on 110VAC, that will take up a large chunk as well if you have it turned ON.
What you are experiencing is "normal" and not cause for alarm.
If you want to operate your A/C, you'll need a 30A circuit.

I am curious, JNKS2010... is your A/C 13,500BTU? Because if it is, and you aren't running any other power pigs (fridge, water heater, microwave, et al), I have found that a (true) 20 amp receptacle, without extension cord will run the A/C, without issues.
Having said that, you don't have much "wiggle" room, as that A/C unit can draw between 12-18 amps.
The best idea is to find a location nearest your main electric panel and add a 30 amp RV receptacle.
Good luck, friend...

thanks for all the reply's. I am relieved that it is working the way it should.

Like Hoef said, it can be done if you are plugging in to a 20A circuit, 15A maybe not.
You should minimize any extension cords and be sure there isn't another load on the residential circuit.
I've done it a few times.

So we have only gone 4 times so far this season. On trip #2 we turned the A/C on and after about an hour or so of being on the unit smelled funny and shut down. When that trip was over we took it directly to the dealer. They ran it for 4 days straight without a hitch. We brought the trailer home and until yesterday morning I went out to clean up the trailer and brain storm on how to fix our dinette from tipping over when being used as a bed. Anyways. I turned on the A/C and about 10 minutes in, it shut down again.

I did some trouble shooting and couldn't get it to work. So we packed her up and off we went to the dealer. Got there. Plugged her in and she ran great for well over an hour. And that's when it hit my wife that we may not have enough juice to run the A/C.

Putting in a 30a plug isn't an option. And honestly we don't plan on using while at home anyways.

I have a dedicated 30 amp circuit at home my trailer is plugged into. Yes, I can run both AC units at once.

thanks CW3...I figured it might be close depending on when they kick on.
