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

Power interruptions can challenge a home, but the right accessory can make backup power feel smoother and more controllable. The XMK Generator Interlock Kit is designed for Siemens and Murray 100 Amp panels, supporting two common spacing configurations used on Plug on Neutral and Non Plug on Neutral models. This kit helps you plan a safe, practical way to switch to generator power when needed, without compromising the integrity of your electrical system.

Why this interlock kit matters

The interlock mechanism prevents both mains and generator power from feeding the panel at the same time. This built‑in safeguard gives you the ability to direct generator power to chosen circuits with clear control, while keeping your home’s electrical system protected. The design also aims for smoother transitions during outages, reducing guesswork when you need to switch power sources.

Key features and what you get in the box

• Compatibility: Works with Siemens and Murray 100 Amp panels, aligning with 7/8 inch spacing on Plug on Neutral models and 1 1/4 inch spacing on Non Plug on Neutral models (verify your panel type).
• Complete kit contents: Interlocking plate, 2 shoulder screws, 3 hex nuts, 1 drill bit, 5 reminder labels, 2 zip ties, and a detailed instruction sheet—everything you need to install and operate safely.

Real‑world use cases

• During a planned outage, you can selectively power essential circuits (lighting, refrigeration, charging devices) without overloading the main panel.
• Pairing with a portable generator, the kit supports a straightforward setup that reduces manual switching and helps family members understand the process.

Installation considerations and safety

The kit is designed for easy integration with your existing panel and moves smoothly in operation once correctly installed. Always confirm the panel model and the correct spacing before starting, then follow the included instructions for a proper fit. This product is a safety accessory and should be used as part of a responsible backup power plan; it does not alter panel ratings or guarantee outage outcomes.
