2. Power Inlet Box connected to a 50 Amp Manual Transfer Switch at an interior distance of 50 wire feet using 8/3 cable, permanently installed.
3. Transfer Switch connected to 200 amp Main service with 8 circuits wired for the portable backup.
I recognize this is small gen set and has limitations in powering part of a residence with only 30 amps. I also recognize the cost of installing 8/3 cable in lieu of placing the gen set closer. 8/3 would allow me to step up later with a larger gen set (50 amps) provided I upgraded the appropriate transfer switch & main panel breakers.
This setup also allows me to take the portable gen set to other property and use it as planned for some rural construction.
