Why generator interlock kit installation comes up in Fayetteville
The January 2009 ice storm left much of Northwest Arkansas without power for more than a week, and homes on the wooded hills of Mount Sequoyah and the rural edges of Washington County still see the longest restorations. A portable generator wired through an outdoor inlet and a breaker interlock lets owners run the furnace blower, well pump, refrigerator and lights without back-feeding the utility's lines. The interlock is a sliding plate that keeps the main and generator breakers from being on together.
The generator must run in the open, well away from windows and doors. Permits come from the City of Fayetteville or Washington County.
- Common setups run the furnace blower, well pump, refrigerator and a few lights from a portable unit through an inlet and interlock, or use a propane standby generator where there is no natural gas.
- Permits in Fayetteville
- Electrical permits inside city limits come from the City of Fayetteville's building safety division; Springdale, Rogers and Bentonville issue their own. Arkansas licenses electricians through the state Board of Electrical Examiners.

Do I need a permit for generator interlock kit installation in Fayetteville?
Usually, yes. Electrical permits inside city limits come from the City of Fayetteville's building safety division; Springdale, Rogers and Bentonville issue their own. Arkansas licenses electricians through the state Board of Electrical Examiners. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Fayetteville?
If the work affects the meter or service, the electrician coordinates with SWEPCO (some areas: Ozarks Electric Cooperative), which owns the meter and service drop.
Is an interlock kit legal?
