dunno why you would want to use it.

if you are just sitting in a driveway etc, 20a is enough to keep the batteries charged. not many people have 2 30a circuits anywhere.

and if you ran off of two 20a circuits, all that means is you could run maybe 2 air conditioners.

i have never used one of them on any of the 3 coaches i have had.

and for the purests out there.....there is no longer 110 v or 220v it is all 120v and 240v.
