Families in Oviedo often want to keep the refrigerator, fans, internet and part of the AC running during outages. A portable generator with an interlock covers the basics; standby generators work for whole-home backup where natural gas or propane is available.

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.

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.
