Want to test AC before heading south - no 30a service.

Thanks all - I'll check it out. I appreciate the input.

We do this often on a 20amp service from family and friends garages. Works out fine. It will trip if we put the hot water on electric or try the microwave or coffee pot. We've learned to manage just fine. We don't turn off the other breakers with 20amp service, but we do when using our 2400 generator. The most surprising draw in our camper is the convertor that charges the battery.

(Just joking, son) Or you could have a qualified electrician install a 30a 120V RV receptacle for you.... but do you trust any "qualified" electricians??? (/joke)

To reiterate: 15A or 20A will do ya, yea, that's the ticket!

Any 15 or 20 amp circuit should operate it providing the A/C is the only thing on the circuit.

Test the generator, rk? Oh!

• Outlet in your garage has 20-amp service. Looks like 15-amp but has a cross-cut in the neutral slot
• Use a 12 gauge extension cord
• Flip breakers inside rig to turn off everything but the A/C
• The A/C should start and run. As long an nothing else is connected the 20 amp breaker will carry the load.

This is what we do.

Ac runs fine and our resindential fridge runs normal also.

Batteries charge, fridge gets cold and ac cools down the rig.

Not only do they start fine, they RE-start fine against high head pressure. This is for testing not a permanent installation.

THIMK!

30 amp to 20 amp

Rigs connect to 30 amp service AND operate their hot water heater, refrigerator, and converter AND the 15K roof air...

I picked up a Kill-A-Watt plug in meter at Harbor Freight on sale a while back. I took the time and plugged it in to my TT AC line using a 30 to 15 amp adapter. The house circuit it plugs into is 20 amp (former submariner, I have all my house circuit breakers and what they supply mapped out ;). My AC is a 13,500 BTU and measured a constant 12 amps on high. Actually 1446 watts.

I did the same till my killawatt burned up.

Turn off all circuit breakers in RV save MAIN and A/C. use a 20 amp circuit and a 12ga extension cord. you can get those at Home Depot, Lowes or Sears/K-mart, The latter has one with a push button on the outlet. I like it.
