TT plugged in at home?

We used to own a 2008 Mallard, and decided to used the A/C on a 110 at home nothing else was on. The A/C was working fine for a while and then stopped working, we made a service call to see what was wrong with the A/C. Because all it was doing was blowing warm air.
He asked me what happened? I told him that I plugged the A/C straight to the 110 to the house, his reply was ok. So he got up on top of the roof and worked on the A/C. Came back down with a small looking Transformer looking part ( I forgot the proper name for it ) it was (FRIED ) he told us whatever you do never use your A/C on a 110 current make sure you have the right 30/50 amp connection. Lesson learned cost $150.00 for about 15 minutes of work.

On another Forum it was determined that the startup current of a Dometic 15K A/C is 13.6 amps with a 2.8 amps run current. That would imply that you can run the 15K A/C off the 20 amp circuit; but don't push it with other `stuff' on the same circuit.

The OP said nothing about the rated capacity of the source he's using, only that it's "a 110 outlet" which of course isn't the case at all as the nominal unloaded source voltage all across N America these days is considered to be +/- 120 vac. If the circuit in question is rated for 20 amp service protected by a 20 amp breaker then of course his chances of successfully starting and running a 15K A/C will be improved over attempting to run it on a 15 amp protected circuit ... but he hasn't provided this information. :R

If you have a 30 amp RV recepticle at the house, you should not ave any issues using a dog bone to adapt to 50 amp.

You should still be able to, however, the smart thing to do is to call an electrician and get at least a 30 amp receptacle installed. Then you can do most anything you want. It will be money well spent.

I'm getting ready to purchase a travel trailer and it may be 50amp and have a 15k btu AC unit. Will I still be able to plug this in at home on 110? At the very lease I want to run the AC.

No. Even in your current situation running a single 13,500 BTU A/C on a 15 amp drop you should be running only the A/C and nothing else. Attempting to run a 15,000 BTU A/C will only worsen the situation.

My camper is a 30 amp with a 15,000 btu air, we run the air 24x7. We did put in a dedicated 30 amp RV line. We never run the air conditioner and microwave at the same time, even in campgrounds, this is the only thing we have to watch when running the air conditioner. Everything else is OK with the air on.

If your camper comes with 50 amp, you can get a step (up) adapter, probably need a couple. A step-up from 20 to 30 plug and then a 30 to 50 amp plug. Then you can plug your camper into the 50 amp adapter plug.

You should be able to run the air conditioner with no problems. But once you reach your household 15 or 20 amp max amount (the breaker) will pop. That's the worst that will happen.

If (when) that happens, then you'll probably need to think about running a dedicated line for the camper with 50 amp service if you want full electric use of your camper.
