My AC source is split phase120/240. It supplies two hot wires and a ground, no neutral. I am using a Victron transformer because I am splitting the two phases into two separate battery chargers for my RV, but I need the loads on the two hot wires to remain balanced. My question is, would it be correct to connect the two hots AND the ground into the autotransformer, and then use the two 120 lines, the new neutral (created by AT), and ground coming from the autotransformer to connect to my loads (battery chargers)? Any potential issues with that set up?
