Why generator interlock kit installation comes up in Eugene
The February 2019 snowstorm brought down trees across Eugene and left many homes without power for days, and a portable generator wired through an outdoor inlet and a breaker interlock is a common way to prepare. It runs the furnace or heat pump air handler, refrigerator and lights without back-feeding EWEB's lines. The generator must run outdoors, away from windows and doors, and sheltered from rain.
Many owners with rooftop solar consider a battery system instead. Permits come from the City of Eugene's building and permit services. Mark the safe circuits.
