Quick one : 30A on 20A circuit, which restrictions?

[vlopddap]

I need a quick advice!! :B

I don't know if subject is clear enough, but I'm going on a camping trip this weekend in a state park and the only campsite available have 20A power hookups. My small 16 feet trailer have a 30A power connection (like most travel trailer). I have the 30A to 20A gender changer as well, but I'm wondering what I can and can't run on a 20A circuit.

First of all, my small TT is a basic trailer so I don't have AC water heater. I have an air conditioning but it's a small household windows/wall mount 5000 BTU A/C. I have a microwave and a small 2.7 cu fridge. Otherwise only the 120V-12V converter run on 120V.

Weather forecast predict a humid and hot weekend, so I'm wondering if I can run my small A/C during the night on a 20A hookups? I know the 2.7 cu fridge only draw 1.5 amps on 120V. I also checked on the Frigidaire brand website (my A/C is Frigidaire brand) and based on technical specs the A/C only draw 4.8 amps in cooling mode.

I ran the A/C yesterday at home (I have a 20A circuit too) for a few minutes without any problem. For sure I'll run A/C only and no other appliances (like microwave or other)...

Just want your advices.

your multi-function surge protector will protect it if the voltage drops too much.

Definitely do this.

You're probably going to a pretty old CG with out-dated and substandard wiring. If all the other rigs are trying to run air, you could have some serious voltage problems.

X2, go camping.

X3, I have a dedicated 20A circuit in the garage that runs our 13.5K AC in the driveway.

You may need to switch off the A/C for the few minutes you run the microwave, but see otherwise don't anticipate a problem.

You should be good to go as the small window AC units easily run off of a 15 amp household circuit. Wouldn't hurt to check voltage drop at campsite with AC running if you have a meter although I suspect it won't drop too low anyway. Have a great time!!!
