Installing a generator is only half the equation—a professionally installed transfer switch ensures you can switch between utility and backup power safely and efficiently. Without a proper transfer switch, you risk dangerous backfeeding that can injure utility workers and damage your equipment.
At Josh LaFerriere Electric, we install both automatic and manual transfer switches, ensuring your generator is connected safely and in full compliance with electrical codes. For emergency situations, having a transfer switch means reliable backup power is always ready.

A transfer switch is an electrical device that connects your generator to your home or business's electrical panel. It allows you to safely switch between utility power and generator power, preventing dangerous backfeeding into the utility grid.
Transfer switches are required by the National Electrical Code (NEC) for any generator connected to a building's electrical system. They are essential for both safety and legal compliance. We handle all electrical upgrades to ensure your system meets current standards.
Designed for standby generators, an ATS automatically detects a power outage and switches your home to generator power within seconds—without you lifting a finger.
Designed for portable generators, a manual transfer switch gives you a safe, code-compliant way to connect your generator to your panel and select which circuits to power.

Josh (and Charlie) provided excellent service. We called for a site visit and an estimate. They got us on the schedule within a week, showed up on time, offered a fair price, and were able to complete the work the same day! After they replaced the electrical panel, they took the time to work with me to test and clearly label each switch.

Josh was professional through and through. He responded quickly, came out to assess my new circuit installation needs and discussed options, clearly listening to my concerns. He then gave me an upfront estimate and got it all done same day. The new run is tidy, he cleaned up thoroughly, and was overall great to work with.

Josh has done two projects for us, including troubleshooting some non-working outlets and installing a new bathroom fan. He’s extremely courteous, professional, reliable, and offers fair pricing. Highly recommend for any electrical needs!
It isolates your home from the grid so your generator cannot backfeed utility lines — a serious safety and legal requirement.
Standby generators use an automatic switch. Portable generators typically use a manual switch or interlock kit.
Yes. We match the switch to your generator and the circuits you want backed up.
Not always. We check space and labeling at the panel. If the panel is obsolete or full, we quote that work separately.
Many transfer-switch jobs are completed in a day once the generator and circuits are chosen.
