I am trying to run a single 50amp 120v line for my travel trailer off of a 6000w power inverter with 4 separate ac plugs-ins. If I attach the 4 black leads from each outlet as well as the 4 white leads and the 4 ground leads to my HD 120v 50amp cable plug, will the load applied at the single plug then be equally split between the 4 outlets on the inverter, or will I burn the inverter up? The power at our campground is not the greatest, so I was hoping to run the trailer off of a pure sine wave inverter running on batteries, being charged from a battery charger in order to stabilize the voltage to the trailer. Any thoughts on this would be greatly appreciated.
