And like I said we are setting here with temps reaching low 90s and have no problems with two 13.5k Dometic on 30A. Yes, we do shut down the rear AC when we run the micro and we do have the water heater on gas, but we have a residential fridge, a 32" TV and all the other normal stuff. We have NOT tripped a ckt breaker once.The Texan wrote:
We are running BOTH 13.5 units on 30A with NO problems, so you will have no problem with a 15 unit. Try running your fan on "high" instead of auto, when in high humidity and that should stop the icing.
Really??? If you look at his photo post, his 13.5 Penguin will pull 15.1 amps at 95 degree ambient on hi cool. His 15k original rear unit will pull 16.1 amps on hi cool at 95 degrees. That puts his TOTAL AC load at 31.2 amps with NOTHING else in his RV on. If the temps go to 105 (they are in Texas right now), his amp draw will go UP 2 more amps to a total of 33.2 amps. Doug
NO, YOU read it again. I see nothing in his post about running his RV on 30 amp service. YOU made the statement about your RV on 30 amp service and I was just letting him know, that almost ALL RV's cannot run 2 AC units on 30 amp service especially his. I will bet if I look at your 50 to 30 adapter, it is burnt and corroded (30 amp side) from the excess amp draw caused by what you are doing. Doug
