Progressive Dynamics 30 Amp Generator Transfer Switch
Automatically transfer 120-volt power from your generator to your RV's electrical distribution panel.
No manual switches to activate-just unplug from the power post,
start your generator and the transfer switch sends power to the
converter and 110-120-volt appliances and accessories. Automatically
senses generator power and prevents two power sources from entering the
AC distribution panel at the same time. Time delay/relay control gives
generator 20-30 seconds to reach safe output level so motors and
compressors don't suffer brownout damage.
