Why generator interlock kit installation comes up in Hattiesburg
For many Hattiesburg households, a portable generator wired through an outdoor inlet and a breaker interlock is the practical way to keep the refrigerator, fans, lights and a window unit running after a storm. The interlock prevents back-feeding Mississippi Power's lines while crews restore service. The generator must run outdoors on dry ground, away from windows and doors.
Student renters near the University of Southern Mississippi should check with the landlord first. Permits come from the City of Hattiesburg's building and permits office. Label the safe circuits on the panel door.

Generator Interlock Kit Installation in Hattiesburg: questions
Do I need a permit for generator interlock kit installation in Hattiesburg?
Usually, yes. Electrical permits inside city limits come from the City of Hattiesburg's building and permits office. Mississippi licenses larger contracting work through the State Board of Contractors, and the city may require a local license. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Hattiesburg?
If the work affects the meter or service, the electrician coordinates with Mississippi Power (some outlying areas: electric cooperatives), which owns the meter and service drop.
Is an interlock kit legal?
Yes, when it is listed for your panel and installed with a permit; it is a recognized way to prevent backfeeding.
