This Progressive Dynamics 5200 Series transfer switch automatically senses when your generator is putting out stable power and switches your RV's AC distribution panel to that source, preventing shore power and generator power from ever feeding the panel at the same time.
A time-delay circuit board holds the transfer until generator voltage has settled, avoiding the power hiccups that can come from switching too soon. Rugged screw-type terminals wire straight to the contactor base, and a removable protective cover with the wiring schematic printed inside makes installation and troubleshooting easier.
A straightforward way to add automatic generator/shore power switching to a 50-amp RV electrical system.
