Generator installation and backup power in Orlando
Interlocks, transfer switches and standby generators for hurricane season.
What this service covers
Safe connection for portable generators with an interlock or transfer switch, standby generators, and load planning for hurricane season. Tell us what you want to keep running and we’ll connect you with an independent electrical contractor.
Permits
This work usually needs an electrical permit from your local permit office: the City of Orlando, Orange County, or your city's building department. The contractor normally pulls it.
Signs and situations
Hurricane-season outages
After Hurricane Milton in October 2024, tens of thousands of Orange County homes lost power. Restoration times vary by storm and utility.
Safe connection
An interlock kit or transfer switch keeps generator power from flowing back into utility lines, which can injure line workers.
Sized to what matters
List the circuits you need most: refrigerator, fans, medical devices, well pump, AC.
Permits
Generator connections need permits. Winter Park, for example, publishes a dedicated generator permit checklist.

Frequently asked questions
No. Feeding power into the house through an outlet with a double-ended cord (backfeeding) energizes your home’s wiring and the utility lines outside. It can electrocute utility line workers and anyone who touches the cord, and it can damage the generator and your appliances when power returns. The safe options are an interlock kit with a generator inlet, or a transfer switch, installed by a licensed electrician with a permit.
Outdoors only. Never run it in a garage, on a porch, in a carport or under a window, even with the door open. Keep it well away from doors, windows and vents so exhaust can’t drift inside, and follow the distance in the generator’s manual. Carbon monoxide has no smell, and poisoning is a well-known danger after hurricanes. Install battery-powered CO alarms inside your home.
Start with what you need to run at the same time: refrigerator, freezer, fans, lights, phone charging, medical devices, a well pump and perhaps a window AC or part of the central AC. Each has a running wattage and a higher starting wattage. An electrician can review the list, check your panel and recommend a connection (interlock or transfer switch) that matches the generator. Whole-home standby systems are sized with a load calculation.
Often, yes. A standby unit fueled by natural gas or propane may also need a gas or fuel permit, a concrete pad and a location that meets setback and clearance rules. Many communities also require HOA approval. Check with your permit office and association before you buy, since these rules can decide where the generator can go.
