The panel on the right is for the generator
it covers 75% of the house including but not limited to
Dryer, furnace/fireplace fan, frig, bathrooms, garage door motors
the essential stuff. around the house I have never had to use it
and only load tested it after i put it in. It's a security blanket that
is in place and ready. I keep the generator starter motor battery
on a float charger and start it every month. also have a pull cord
smaller generator as a back up....just in case?
