I have 2 multiplus connected to rv 50amp 240 but I have a onan generator 5500 120v. A trasnfer switch is installed and the shore power goes to a transfer input , the generator goes to the other power input and the output to the panel.But when i look at other wire diagrams it dont seem right. also can I run power to the multiplus and t-tap off to the transfer switch that way the multiplus doesnt have to be on to power up the rv when plugged in.
