Why generator interlock kit installation comes up in Mobile
A portable generator connected through an outdoor inlet and a breaker interlock is how many Mobile households ride out hurricane outages without a standby unit. It can run the refrigerator, fans, lights and a window AC unit. The interlock blocks the main breaker while the generator is connected, so power cannot back-feed into Alabama Power's lines during restoration.
The inlet goes on an outside wall where the generator can run in the open, raised off wet ground and away from windows. Permits come from the City of Mobile's central permitting office.
- Portable generators connected through an inlet and interlock are the lower-cost option for essential circuits.
