Hello. I recently put one of these Automatic Transfer Switches in my RV in front of the SP6548 so that I could use 50 amp service normally while still running 120v over to the AIO to charge batteries. Right now everything seems to be working, however, I have not wired in the control relay wiring yet for the "automatic" part of this whole thing. The idea is that during 50 or 30 amp service, normal input will be powered and should provide entire trailer + inverter with power... If I use anything else such as generator or regular 15 amp 120 I'm going to go directly to the EG4 chargeverter straight to the batteries and let the AIO supply the entire trailer with power, or when I have panels on top let the solar power it. I'd rather not have to select this back and forth manually.
As you can see the control wiring ports are very small and I was wanting to make sure there shouldn't be any reason to have to use anything larger than like 16 - 14 gauge for that relay connection right, I am not aware of what kind of current should go through that and it was not included. I am indeed using this switch outside of what it was built for but I needed a 4 pole dual throw and could not find anything else that seemed to fit at at least 50 amps.
