Why generator interlock kit installation comes up in Cheyenne
Blizzards and wind events on the high plains can knock out power in Cheyenne during deep cold, when a furnace without power becomes a safety issue within hours. A portable generator wired through an outdoor inlet and a breaker interlock lets homeowners run the furnace, refrigerator and lights without back-feeding Black Hills Energy's lines. In Cheyenne's wind, the generator needs a sheltered, level spot outdoors, clear of drifting snow and away from windows.
Permits come from the City of Cheyenne's building safety department. Label the safe circuits. Store the cord dry.
