A/C and fridge

I was wondering if I can run both a/c and fridge while plugged into my home 110 shore power? 30 amp w/adapter. Didn't know how much power the fridge draws, wanted to run them both to get ready for a weekend outing.

The short answer is "probably". Since you'll be traveling anyway, why not run the fridge on propane. The refrigerator is one appliance that is easy on propane.

No problem at all. I do it all the time. I'll normally start it on propane for a few hours since it cools down better, then switch it to auto and leave it.

Are you plugging into a 30 amp receptacle and using a 30 to 50 amp adapter?
If so, then there's no problem running both.

I take it he has a 30 amp camper and using a 15 amp adapter.
If thats the case I'd not run the a/c and fridge on 120v

Correct, 30 amp with 15 amp adapter. I ran it today and all is good . Should I turn off the fridge? Will it blow a fuse or what? Sorry for the newbe questions.

If it was going to blow a fuse, it probably would have pretty quickly.
Risks: check the extension cord and adapter for heat, I once melted a 30 to 15 amp adapter plugging into my brother's garage and running the air.
Running the air on low voltage can shorten the life of the compressor significantly.
When running that A/C, you'll want to minimize the current draw; don't run microwave or water heater, or even a lot of lights.

Be certain your extension cord, if you use one, is 12 guage. That is rated for up to 20 amps. The house outlet could be 15 or 20 amps. Look at the breaker in the house to know for sure.

I run a/c and fridge together often. My home outlet is 20 amp.

If the fridge heater is on and the AC restarts ( after running then a brief off period) it may trip the breaker in the house if you have it plugged into a house outlet on a 15A breaker. Also what else in the house is on that breaker. For example if it is a garage outlet and both items are running in the trailer and you operate the garage door opener it will trip the house breaker.

My Dometic RV fridge draws a little less than 300W of AC power when cooling. This should be around 2.5A at 120V. A 15A circuit would have around 10+A available for the air conditioner which would be a little over 1200W, very close to what it's rated to draw.

Overall, it should work. If the circuit breaker trips when the A/C compressor kicks in, you'll need to move the power cord to a 20A circuit. As already recommended, run the fridge on propane and you'll definitely have no issues running the A/C unit. If you're plugged in at home, you could always run the AC during the day and switch to the fridge at night. This also gives you an excuse to get into the unit twice a day to verify that all is well.
