Working well. I had to contact their customer service regarding the fact that my main is at the bottom of the Load Center and not at the top. They advised me what to do and the installation went easily.

Easy to install, and I was pleased that a drill bit was included. Being my electrical main is part of the standard panel, this was exactly what I needed. Took about 15 minutes to install.

I needed to install an interlock kit on my Cutler Hammer 200-amp vertical throw panel so I could safely connect my home battery backup (an Anker Solix F3800). My photo shows that the interlock is a perfect fit for my panel, and it does its one job of not allowing the main breaker and the generator inlet breaker to be enabled at the same time. I had the interlock and the 50 amp generator inlet beside it installed by a local electrician for about $150. Now I have a whole-house battery backup that's a little less automatic than a Tesla Powerwall or a Generac whole-house generator, but it was a fraction of the cost to set this up.

I installed this item into my breaker box in less than an hour. I must admit that I was questioning whether it was going to work properly, but once installed it worked as it was supposed to. The directions supplied are concise and easy to understand and the price was fabulous. I've tested my generator and with this item & I can safely run my entire house. Sturdy metal construction.
