Generator Interlock Kit Compatible with Siemens or Murray 150 or 200 Amp Panels, 7/8-1 1/4″ Spacing Between Main and Branch Breakers

Description

Product Overview

The XMK Generator Interlock Kit is engineered specifically for Siemens and Murray load centers rated at 150 or 200 amps. Crafted from high‑grade steel, the interlock plate offers exceptional durability while maintaining a lightweight profile for easy handling. The kit accommodates a breaker spacing of 7/8 to 1¼ inches, ensuring a precise fit on panels that meet this specification. Each component – from the interlocking plate to the shoulder screws, hex nuts, drill bit, reminder labels, and zip ties – is manufactured to exact tolerances, guaranteeing a secure lockout that prevents the main breaker and generator breaker from being engaged simultaneously. This safety mechanism protects both the electrical system and the user by eliminating the risk of back‑feeding power into the grid, a critical concern for portable generator owners.

Usage

Homeowners, RV enthusiasts, and small‑business operators who rely on portable generators for emergency power will find this interlock kit indispensable. Once installed, the kit allows the generator to be connected directly to the home’s electrical panel, enabling the selective powering of essential circuits such as lighting, refrigeration, and heating during an outage. The kit’s universal design works with both Siemens and Murray panels, making it a versatile solution for a wide range of existing installations. Because the interlock plate is mounted directly onto the panel, there is no need for additional external enclosures or complex wiring, simplifying the process and reducing potential points of failure. The kit is also ideal for seasonal use, as it can be easily removed and stored when the generator is not needed.
