XMK Generator Interlock Kit for Siemens/Murray 100A Panels – 7/8 to 1 1/4 Inch Spacing

Overview

The XMK Generator Interlock Kit is designed to help you coordinate power between your main breaker and a generator on Siemens or Murray 100 Amp panels. It supports two common spacing options and is built to be straightforward to install, making outage readiness more approachable for homeowners and DIY enthusiasts alike.

Rather than a single rigid configuration, this kit accommodates both Plug-on Neutral (7/8 inch spacing) and non-Plug-on Neutral (1 1/4 inch spacing) panels. Before you begin, double‑check your panel model and the spacing your panel requires to ensure a proper fit. The result is a practical, scalable solution that aligns with how you use power during a backup scenario.

Why this interlock kit matters

• Designed to prevent both mains and generator power from energizing the panel at the same time, reducing the risk of backfeed on outages.
• Helps you direct generator power to selected circuits safely, allowing you to run essential appliances without overloading the system.
• Compatible with Siemens and Murray 100 Amp panels, covering many common residential setups.

Concrete benefits and real‑world use

In everyday terms, this interlock kit offers a way to manage multiple power sources with clearer, safer switching. While outcomes can vary by home and setup, the interlock concept is intended to help you keep essential devices running while avoiding simultaneous power from two sources.

Two common spacing options cover a wide range of panel types, and the included components give you everything needed for a complete installation. If you’re not completely confident in working with electrical panels, consider professional installation to ensure a tidy result and to verify compatibility with your specific panel model.
