How do I get 220 volts out of my Onan?
I (actually my chief engineer) split the two coils to provide separate 110 to two separate circuits. Two 110 hots and a ground give you 220 if needed. In the installation manual for BGE, NHE Gensets Manual #965-0628 of 2-92 page 7-4 the schematic #611-1206 for 60HZ generator. He moved: T4 From L0 to L2 T3 From L1 to L0 CB2 From L1 to L2 This is a totally unauthorized switch and what you do is up to you.
