Why generator interlock kit installation comes up in Springfield
The October 2011 snowstorm, which dropped heavy wet snow on trees still in leaf, left most of Springfield without power for days, and many homeowners have since set up a portable generator with an outdoor inlet and a breaker interlock. It runs the boiler or furnace, refrigerator, sump pump and lights without back-feeding Eversource's lines. In multi-family homes, each unit's service needs its own setup.
The generator must run outdoors, away from windows and doors, and clear of snow. Permits come from the city's Code Enforcement building division.
- A portable generator through an outdoor inlet and panel interlock covers those, while a natural-gas standby generator with an automatic transfer switch runs automatically.
