A generator interlock system is a safety device that allows you to connect a portable generator to your home’s electrical panel in a controlled and code-compliant way. It ensures that the main breaker and generator breaker cannot be on at the same time, preventing dangerous backfeeding into the utility grid. Interlock kits are typically installed directly on your electrical panel and are a cost-effective alternative to traditional transfer switches. When the power goes out, you simply turn off the main breaker, slide the interlock to expose the generator breaker, and power selected circuits safely. It’s a reliable solution for homeowners who want to use a generator during outages without complicated wiring or risk.
