Amp draw on ac unit

[rvgolfer]

I was wondering what kind of running amp draw there is on a 15,000 a/c unit.

Dometic lists "Compresser loaded amps" on thier 15000btu units at between 12 and 13 amps in this brochure Also a fan loaded amp draw of around 3.5amps so you would be looking at around 15 to 18 total depending on unit.

Do not forget that start up ampreage can be significantly higher, which would open a breaker with other loads drawing off the circuit. Later,

Thats cool because last night i had it in the drive way plugged in and it ran for about 20-30 min. And it tripped the house breaker. But its only a 15 amp circuit. Now it makes sense. Thanks for the info.

Keep in mind it is possible to trip the TT or 30 amp campground breaker. I had this happen once. The ac, tv and microwave were on and I turned on the hot water. When the electric element in the water heater kicked on the breaker in the TT tripped. I am glad I had read a post here about this or I would spent considerable time troubleshooting a nonexisting problem.

Ours will aslo trip the breaker in the driveway but only if I am using an extension cord plugged into the Camper power cable. If I use the power cable adapter plugged directly into the same outlet on ny house (15A GFCI) then the AC will run all day and never trip the breaker.
