Adding a 3rd AC Unit

Good feedback.
The reason I wanted to add a seperate line to connect the 3rd AC unit to a 30 amp when parked using shorepower, is because I did not want to overload the coach circuits.
Last year I had 2 roof ac's and 1 portable ac running, along with fridge, and other items,(no hairdryer or oven, just normal stuff) and the50 amp protection box
tripped and shut off all power to the RV.
So I think I was drawing to many amps and it shut down.
With the 3rd AC going to the 30 amp connection I remove the amps this unit draws through the coach circuits.
Make sense ?
:h
As usual I'm confuse. Are you referring to the 50 amp outlet on the outside power pedestal or do you have some type of EMS?
If you have an EMS it could have shut down because of a low voltage condition which is very common at parks durning summer months. Also if you power your third AC off of the pedestal you would not have it protected and could easily damage it from low voltage.
Your 50 amp circuit should handle all three ACs without problems. I've only encountered one problem when using all three of our ACs running. We had the clothes dryer on, TV on, surround sound on and convection oven on at the same time without issue. Then my wife plugged in her curling iron. Our progressive EMS shutdown everything because of low voltage.
If you don't have an EMS I highly suggest you get one.
