Good, and easy to install, but if you don't know what that stuff is behind the panel, don't do it yourself. Even when you turn off the main breaker, those big wires are still hot and can hurt you. This will stop larger surges, but you still want a smaller per-appliance surge protector on the smaller stuff.

Decided to install this in my circuit breaker boxes after doing some research and losing some of my kitchen appliances to power surges. Sadly, most people don't realize this is a necessity today and you need to install layering surge protection in your household as everything is pretty much electronic based today. Ironic no one ever mentioned protecting my household appliances and electronics when purchasing them with a whole house surge unit like this? It's way cheaper than finding out the hard way and replacing your expensive electronic equipment due to lightning hits nearby and power surges. I would highly recommend installing a whole house lightning arrestor, along with these main panel surge protectors and quality name brand surge protection strips on any sensitive electronic equipment in your house unless you don't care.

If you have a Square D QO breaker box with space for a 220V breaker, this surge protector is for you. Mount it as close to the main breaker as possible. Move breakers if necessary. Don't forget that you will still require surge protection at each electronic device that needs to be protected inside of you house. That means anything that contains a circuit board. Switch Main Breaker to OFF when installing!
