Square D Interlock Kits

Square D was established in 1902 in Detroit, Michigan, and became a trusted name in circuit breakers and safety devices before joining Schneider Electric in 1991. The brand is also known for solutions like the generator interlock for Square D panel, which enhance home backup power safety. Many electricians rely on the Square D interlock kit for dependable and code-compliant installations.

We’ve specially designed several Interlock Kits to work with Square D electrical panels. Each Kit acts like a manual transfer switch, allowing you to quickly, easily, and safely connect your portable generator to your home’s electrical panel. Compared to standard transfer switches, our Kits can be installed more quickly so your installation costs should be lower, too.

We’re proud to say that our Interlock Kits are made here in the USA.
