I used to have an old National Sea Breeze 30 amp with 2 ac units. All other items that run on ac need to be shut off. Then, if the pedestal is in good shape, you could do it. You must remember, a 30 amp circuit is 110 volts ac. A 50 amp circuit has 2 110 volt legs at 50 amp each, like you have at home. Electrical panel determines what runs off of each leg. Dogbone converter connects both 110 legs of 50 amp plug to single thirty amp source....and then (as previously mentioned) there are 208 volt circuits.

One trick I did with the Sea Breeze was to isolate the rear ac circuit. Installed a standard 110 plug and wire connected to the ac to the outside of the rig. I would plug both into the two plugs on the pedestal. Worked great in July in Tuscon.
