Interlock Kit Installation for 13KW Duramax – Punta Gorda, FL

PROJECT DESCRIPTION: INTERLOCK KIT INSTALLATION FOR 13KW DURAMAX – PUNTA GORDA, FL

Coharbor Electric recently completed a generator interlock kit installation in Punta Gorda, FL. The homeowner needed a safe and affordable way to connect their 13KW Duramax portable generator to their home’s electrical system for storm season. Instead of a costly automatic transfer switch, we recommended and installed a UL-listed interlock kit that works seamlessly with the existing panel.

• Installed a UL-listed interlock kit compatible with the existing electrical panel
• Connected the 13KW Duramax portable generator to the service panel via a power inlet box
• Verified grounding, bonding, and breaker sizing per NEC standards
• Added clear circuit labels for generator-powered loads
• Performed a full test run to ensure safe switching between utility and generator power

The homeowner now has a code-compliant, safe, and user-friendly generator hookup. With the interlock kit, they can easily power essential loads—such as lights, refrigerators, and outlets—without risking dangerous backfeed into the utility grid. This setup provides security and peace of mind during power outages.

Why choose an interlock kit?
An interlock kit is a cost-effective, code-compliant alternative to a transfer switch. It prevents both the utility breaker and generator breaker from being on at the same time.

How long does installation take?
On average, 3–4 hours depending on panel compatibility and setup needs.

Will it work with my panel?
Most panels can accept an interlock kit, but compatibility must be checked by a licensed electrician first.

Can I choose which circuits to power?
Yes. You’ll select which circuits run on the generator based on its capacity (13KW in this case).

Is it safe for utility workers?
Yes. The interlock mechanism ensures the generator cannot backfeed into the grid, protecting both your home and utility crews.
