Electrical panel interlock switch.

I have a murray 100 amp main breaker box and the interlock switch fit perfectly over the 100 amp breaker. The interlock kit is a less expensive alternative to transfer switches and generator sub panels. These interlock kits are designed specifically to work with siemens electrical panels. Only allow the the generator breaker to be switched on if the main breaker is off.

I did have to grind the panel cover a small amount to get around the rocker arm it s a tight fit. The rocker arm controls the 30 amp breaker below the 100 amp breaker by keeping it shut off while the main 100 amp is on and vice versa. National electrical code requires a system in place that prevents an emergency generator from feeding back into the utility line. A generator interlock will.

The interlock kit allows you to safely disconnect your panel from the utility feed and switch it over to the generator which is being fed through a new generator breaker. Thankfully there s a solution a way to connect your generator to your panel without a transfer switch.
