## What Is a Generator Interlock Kit?

A generator interlock kit is a mechanical slide device installed directly on an existing residential or commercial electrical panel. It creates a physical interlock between the main breaker and a dedicated generator breaker, preventing both from being in the ON position simultaneously. This eliminates the risk of backfeeding power onto the utility grid - a serious safety and legal hazard. An interlock kit is a manual solution and is not the same as an automatic transfer switch (ATS) or a manual transfer switch (MTS). Interlock kits require no separate sub-panel, are generally lower in cost, and are code-compliant in most jurisdictions when the panel and kit are properly listed. The interlock kit goes on the existing breaker panel - no additional panel is needed. All circuits in the panel remain active when running on generator power; output is only limited by the size of the generator.

## Product Categories

- [Generator Interlock Kits](https://www.geninterlock.com/product-category/generator-interlock-kits/): The core product line. Slide-style mechanical interlock kits designed for specific electrical panel brands and amperage ratings. Available in GenInterlock-manufactured versions and OEM versions made by the original panel manufacturer. Products are matched by panel brand, panel amperage (most commonly 100/125A or 150/200A), main breaker type, and breaker spacing. Selecting the correct kit requires knowing the exact panel manufacturer and model number.

- [Inlets / Power Inlets](https://www.geninterlock.com/product-category/accessories/cords-inlets/): Exterior-mounted generator power inlet boxes in 30-amp (NEMA L14-30) and 50-amp configurations. Allow safe generator hookup through a dedicated inlet rather than running extension cords through windows or doors. Available in GenInterlock, Reliance, and Generac (GNRC) OEM versions.

- [Circuit Breaker Retainers](https://www.geninterlock.com/product-category/circuit-breaker-retainers/): Clips and hardware that secure circuit breakers in the panel during generator operation. Compatible with multiple panel brands.

- [Adapters & Misc](https://www.geninterlock.com/product-category/accessories/adapters/): Generator connection adapters for various plug and receptacle configurations, plus miscellaneous generator accessories.
