Air Conditioner Current Draw
I just bought a new TT and it has a 15K BTU Dometic air conditioner. The Jayco I traded in had a 13.5K BTU Coleman (Airxcel) unit. According to the manufacturer's specs the 15K Dometic draws less ...

OK folks, I just made some interesting observations.
I went out and set the thermostat up to 75 and put the fan in the auto position so it would cycle off and on with the a/c. I watched several cycles.
Every time the fan would come on (2.1A) and run for about 10 seconds. Then the compressor would kick on and only draw about 9A. It would gradually (over 4-5 seconds) taper up to around 15A and then stay there. It never indicated any kind of "start surge" like I was expecting. Maybe Dometic has added some logic in the a/c or in the thermostat that prevents the high current surge that normally accompanies compressor start up. At any rate, the Honda is not having any problem running this 15K BTU unit.
