Why generator interlock kit installation comes up in Jacksonville
A portable generator wired through an outdoor inlet box and a breaker interlock is the budget-friendly way many Jacksonville homeowners keep the refrigerator, fans, lights and a window unit running after a hurricane. The interlock is a sliding plate that makes it impossible to turn on the generator breaker while the main is on, so power cannot flow back into JEA's lines. The inlet is mounted on an outside wall where the generator can sit in the open, well away from windows.
Florida requires licensed electrical contractors, and the city's Building Inspection Division issues the permit.
