does a 12K unit have a 50 amp feed (4 wire) or 30 (3 wire)like a 8K?? if it has a 50 amp feed just like the shore power you could tap in to the system fairly easy
if its the same as a 30amp 8K you wont get 240V nohow
Thats the kind of thing I would like to find out BEFORE we start working on this. I have heard various versions of this. I need 240 volts to make it work the way he wants or he'll be stuck with essentially what I have (120) but at higher current. EVSE's will run fine on 120 but most have a 12 amp pilot signal to the car when running on 120. There are some that send a 32 amp pilot to the car on 120 but obviously it is still half the speed of 32 amps at 240. I need somebody to measure across the breakers on a coach with a 12K Onan. Takers??

Like I suggested if the 12K has two 120V( hot) outputs like a 50 amp shore power has You can get your 240 if It only has one like a 30 amp system then you can not
U understand, I am going to have to wait until I see it before I can make plans. I like the idea of picking it off at the transfer switch though. Assuming there is space close by I can mount a box with a breaker. I'm thinking this through and the worst case is it is 120 and we go with a single 40 amp breaker. He'll have to pick an EVSE with a variable 120 output that can send a 32 amp pilot to the car so the car knows what to pull. It's not exactly what he wants (half as fast) but for what he needs it to do as as often as he needs it to do it it should work. ....but lets hope it is a 240 output.
