Flngr Generator Interlock Kit for Eaton or Cutler Hammer CH Series — 150-200A, 2-1/4 in Spacing

Overview

Meet the Flngr Generator Interlock Kit, engineered for safety and compatibility with Eaton and Cutler Hammer CH-Series panels that use a single vertical-throw main breaker. The kit maintains a precise 2 1/4 inch separation between the main and generator breakers, a spacing that's easy to verify at a glance and supports tidy panel presentation.

How it works

When a generator is added to a home electrical system, the interlock ensures only one source powers the panel at a time. The design prevents backfeed and reduces the risk of unintended energization, while providing a clear method to direct generator power to selected circuits. This approach aims to keep your wiring organized and help you keep confidence when you need to switch sources.

Key compatibility notes: this kit is designed for panels with a single vertical-throw main breaker and 2 1/4 inch spacing. It is not a universal fit for every configuration, so confirming panel type before purchase is recommended.
