Why generator interlock kit installation comes up in Waterbury
After the October 2011 snowstorm left most of Waterbury without power for days, many homeowners added a portable generator setup with an outdoor inlet and a breaker interlock. It keeps the boiler or furnace, refrigerator, sump pump and a few lights running without back-feeding Eversource's lines, which protects line crews during restoration. In a triple-decker, each unit's service needs its own setup or the owner backs up only one unit.
The generator must run outdoors, clear of snow and away from windows and doors. Permits come from the City of Waterbury's building department.
- A portable generator connected through an outdoor inlet and panel interlock covers those, while a natural-gas or propane standby generator with an automatic transfer switch runs automatically.
