Manual Interlock Systems

agency

Spokane Generators is an expert when it comes to manual interlock systems for portable generators. Without an expensive transfer switch, you can't safely plug your portable generator into your home's electrical panel. So, when the power goes out, your household systems and devices won't get generator power through your home's electrical system. That almost defeats the purpose of having your portable generator.

Instead, you'll need extension cords to connect your household devices to your generator. Running these cords through your home creates the hazards of tripping and falling, or even causing a fire. Other machines, such as your furnace or water heater, can't be connected by a cord. These devices simply won't work until power is restored.

Thankfully, there's a way to connect your generator to your panel without a transfer switch, the manual interlock system. A manual interlock system is a less expensive alternative to transfer switches and generator sub-panels. One of our electricians can easily mount the interlock system to your existing electrical panel. Once the interlock is installed, you'll be able to safely and conveniently power household systems and devices through your electrical system.

The manual interlock system is simple and ingenious, it provides a mechanical interlock, which acts as a manual transfer switch so that the utility and generator breakers cannot be turned on at the same time. The interlock also isolates the two systems so that power from the generator will never back feed into utility lines, and vice-versa. That's safer for your portable generator, your electrical system, and electrical workers.
