XMK Generator Interlock Kit for Eaton CH Panels (Tan Breakers) – 150/200A, 1.5-Inch Spacing

Overview

Meet the XMK Generator Interlock Kit, designed to fit Eaton Cutler Hammer CH series panels that use tan breakers with a depressed main area. This precise kit helps you configure a safe, code-aware backfeed setup when you need portable generator power during outages.

Compatibility and Fit

Designed specifically for CH series panels with tan breakers and a depressed main-breaker area, this kit avoids incompatible panels. Before you order, check that the main area is depressed and that your panel is CH-series with tan breakers.

• Works with 150 and 200 amp CH panels
• Requires a depressed main-breaker area
• Not suitable for CH panels with PON breakers where the main is flat or raised

Key Features

The interlock provides a single-handle horizontal throw with 1.5 inches space between the main and the branch breakers. This ensures a clear, safe path for generator power while preventing simultaneous ON states.

• Safe backfeeding by design
• Cost-effective backup power option
• Smooth operation and reliable engagement
• Includes complete hardware and clear instructions

What’s in the Box

Each kit includes: 1 interlocking plate, 3 shoulder screws, 3 hex nuts, 1 matching drill bit, 5 reminder labels, 2 zip ties, 1 instruction card, and XMK’s support for a satisfying experience. The kit is designed for quick, straightforward installation.

Real-Life Scenarios

During a power outage, you connect a portable generator to your home’s electrical panel. The interlock keeps your main breaker from closing while the generator breaker is ON, reducing risk while you power essential loads.

Why Choose XMK

Beyond compatibility, this kit offers a practical, off-the-shelf solution that makes it feasible to backfeed safely without custom fabrication. While results depend on your setup and local codes, many homeowners find it a sensible path to temporary power.
