Why generator interlock kit installation comes up in Lexington
The February 2003 ice storm left much of Lexington without power for days, and winter storms still bring outages. A portable generator wired through an outdoor inlet and a breaker interlock lets homeowners run the furnace blower, refrigerator, sump pump and lights without back-feeding Kentucky Utilities' lines, which protects crews during restoration. The interlock is a mechanical plate that keeps the main and generator breakers from being on together.
The generator must run outdoors, away from windows and doors. Permits come from the Division of Building Inspection. Horse-farm properties on the edge of town may need well pumps included.
- In winter the furnace blower, sump pump and refrigerator are the usual priorities, which a portable generator can run through an exterior inlet and panel interlock.
- Permits in Lexington
- Lexington and Fayette County share a merged urban county government, and electrical permits come from its Division of Building Inspection. Kentucky licenses electricians through the state Department of Housing, Buildings and Construction.
