This past June, I was in Ft. Lost in the woods Missouri and it was brutally hot and humid. We have a 35 foot TT and a 13.5 AC unit on it. In CO it just keeps up but in MO we felt like we were dying. I met a guy who had a 33-foot fiver and also had a 13.5 AC unit but he had installed an 8K unit in his bedroom. It was not wired through his rig but rather he had a pig tail on it that hung off of the side of the rig and he plugged into an extension cord which then went to the pedestal. We both have 30 amp service. My question is would a normal 30 amp pedestal handle the 13.5 main AC unit and the 8K unit plugged into the normal 110 hook up. I failed to look at the way the guy plugged into the pedestal so I am hoping someone could tell me as I think this is a good solution for when we need extra AC.
Most of the time an RV campground pedestal can handle the two ACs. We wired our trailer with two 30A outlets and cords one is plugged into the 30A outlet the other into the 50A outlet.
The pictures show our second outlet the breaker panel and one of the additional outlets added for a second frig. second AC not shown, and other misc.
If the pedestal only has one 30A and no 50A you will be more limited but so would a 50A trailer.
In most campgrounds, the 30 pedestal can supply about 30 amps total. There are two outlets and two breakers to allow both RV's and tents to have electricity. They usually can not both be used to increase the load capacity to over 30A. This is especially true in busy campgrounds as there is usually a 100A breaker ( in a locked panel) up stream that protects three 30A pedestals. If you ran nothing ( no converter, lights, tv, microwave etc) but the two ACs, you might be OK.
I have a 50 amp rig with two ac units: one 15,000 and one 13,500. I often run both ac units when at a campground with only 30 amp service, however I do restrict other electrical usage.
Both ac units consume less than 30 amps.
I also run one ac unit (even the 15,000) when plugged into a regular 20 amp receptacle. Debunking yet another Internet myth.
It's all about the amps. A good EMS unit provides a lot of protection, but it also tells you how many amps you are drawing. I have a PI unit and highly recommend them.
