Power Inlet Box • Interlock Kit • Transfer Switch • Safe & Code-Compliant • Permit & Inspection Included
If you own a portable generator and want to power more than just a few extension cords during a hurricane outage, a generator inlet (also called a power inlet box) is the right solution. It lets you connect your generator to your home’s wiring through a single heavy-duty cord — powering your critical circuits safely and legally.
A generator inlet installation includes a weatherproof inlet box mounted outside your home, a dedicated circuit back to your main panel, and either a manual transfer switch or an interlock kit that prevents backfeeding onto the utility line. Backfeeding is illegal, dangerous to utility workers, and can destroy your generator when utility power is restored. A properly installed inlet eliminates all of those risks and makes your portable generator genuinely useful during a storm.
The most cost-effective solution. A mechanical interlock on your main panel prevents the main breaker and generator breaker from being on simultaneously — eliminating backfeed risk. You manually select which circuits to power by switching individual breakers.
A dedicated transfer switch panel with 6–10 pre-selected circuits (A/C, fridge, lights, outlets) that transfers cleanly from utility to generator power. More convenient than an interlock — you flip one switch instead of managing individual breakers.
If you’re planning to eventually upgrade to a whole-home Generac standby generator, we can position your inlet and transfer switch to make that future upgrade easier and less expensive. Ask about the upgrade path during your estimate.
All prices include the inlet box, wiring, interlock or transfer switch, permit, and inspection.
Weatherproof inlet box, dedicated circuit, panel interlock, permit, and inspection. Most straightforward installations in Cape Coral and Fort Myers fall in this range.
Adds a dedicated 6–10 circuit transfer switch panel for greater convenience. Price varies by number of circuits and panel location. Includes permit and inspection.
The right inlet size depends on your generator's outlet rating. We install both 30A and 50A inlets throughout Southwest Florida.
