Why generator interlock kit installation comes up in Grand Rapids
West Michigan ice storms and summer windstorms can knock out power in Grand Rapids for days, and many homeowners use a portable generator connected through an outdoor inlet and a breaker interlock to keep the furnace, sump pump, refrigerator and lights running. The interlock prevents back-feeding Consumers Energy's lines, which protects crews during restoration. The generator must run outdoors, away from windows and doors, and clear of snow.
Permits come from the City of Grand Rapids' development center. Ask the electrician to label the circuits the generator can carry, and keep a cord sized for the inlet stored where it stays dry through winter.
