XMK Generator Interlock Kit for Eaton Cutler Hammer CH Series 150/200A TAN Breaker – 1.5" Horizontal Main-Generator Spacing

Enhance safety and control during power outages with the XMK Generator Interlock Kit for Eaton Cutler Hammer CH panels.

This interlock kit is designed for CH series panels that use TAN breakers and feature a depressed area around the left-right main breaker. It adds a precise 1.5-inch spacing between the main and generator breakers, enabling safe backfeeding with a portable generator. The system helps you manage power flow without simultaneous operation of both breakers, supporting a more controlled and responsive backup setup during outages.

With a focus on practical installation and reliable performance, the kit offers a compact, rugged solution that blends with CH panel layouts. It’s intended for everyday readiness, giving you a possible option to run essential appliances when the grid is down, while keeping safety considerations front and center.

• Compatible Models: CH series panels rated at 150 or 200 amps with TAN breakers and a depressed main-breaker area.
• Not compatible with CH panels that use PON breakers or have a flat/raised main-breaker area.
• Spacing requirement: 1.5 inches between the main breaker and the generator branch breaker.
• Please verify panel model and space to confirm best fit before purchase.

Ease of installation and daily use

The kit is designed for straightforward installation with common hand tools. When the interlock is engaged, the generator back-feed circuit breaker cannot be on at the same time as the main breaker, reducing risk during power restoration. The mechanism moves smoothly and remains secure in both the “generator-on” and “main-on” states, helping to streamline backup power management for households.

Real-world use situations emphasize practicality: during outages, you can back up essential loads in a controlled fashion while utility crews work on the grid. The included labels provide clear guidance for startup procedures and safety reminders, supporting responsible operation and quick reference in stressful moments.

Designed for CH panels with TAN breakers and a suitable main area, this kit offers a cost-effective path to safer generator backfeeding. It complements existing electrical setups by adding a safe interlock mechanism without requiring extensive rewiring. While it does not guarantee outcomes, it supports informed, cautious power management during emergencies.
