Why generator interlock kit installation comes up in Cedar Rapids

A portable generator wired through an outdoor inlet and a breaker interlock can run the refrigerator, sump pump, fans and lights without back-feeding Alliant Energy's lines. The interlock is a mechanical plate that keeps the main and generator breakers from being on at once.
