I have used a cheater box several times. The way they work is they allow one circuit to power one of the hot prongs of the 50 amp plug, and the other circuit to power the other prong. There are a couple of things to remember, if you use a 20 amp and a 30 amp circuit then 1/2 of the distribution box in the bus will be powered by the 30 amp plug and the other will be powered by the 20 amp plug. That will give the bus 1/2 the power that you get when plugged into a 50 amp plug, because when plugged into a true 50 amp plug each leg is powered by 50 amp 120V.

You have to make sure that neither circuit is reverse polarity or as soon as you plug the cheater box in it will create a short, and if either circuit is a GFI the cheater plug will not work, it will just trip the GFI.

It may sounds scary, but it is not. They work well. As I have said I have used them many times.

Hope this helps.
