This is a very simple product to install; it comes with everything you need in the package to install it properly. I have installed several breaker interlock kits, 2 of them being this brand here, and I can say that these are by far the best I have used. Yes, they may seem a little pricey, but I only needed to consider two things to easily conclude this product is worth every penny: firstly, it is for SAFETY! It ensures that only one source can be sending power to your electrical panel (either utility power OR generator power). This ensures safety of those in the home, AND the safety of utility linemen working on the power lines. Secondly, this interlock kit is a fraction-of-the-cost alternative to, and much much less labor intensive to install than the more popular generator transfer switch panel. As for this model in particular, there are multiple reasons to choose this brand over the Murray/Siemens OEM option. The OEM is thinner, cheaper metal, has more pieces, is more confusing to install, and worst of all forces you to waste 2 breaker spots on your panel (spots 2 and 4). Yes, that is two breaker spots IN ADDITION to the two you have to use for the breaker for the generator power inlet. The Generator Interlock Kit here is none of that. It is made of thick metal, yet brilliantly designed to do what it is supposed to without hogging 2 unnecessary breaker spots. I highly recommend this kit and will likely only buy this brand going forward.Read full review

Poor design doesn't allow for the top two breakers on the right hand column of the breaker box to be installed without modifying Interlock. Also has adjusters (can be seen in product photo at bottom of breaker) that are suppose to go between the generator breaker and the next breaker down but there is no room between breakers for it to fit. I modified mine (cut off extra and removed adjusters) enabling breaker to fit and breakers on right side of box to be installed. Still works as designed, not able to turn on Main breaker when in generator breaker is in use and must turn off generator breaker to turn Main back on. A little hard to install due to half goes behind panel and the slide locks go in front of panel but I managed and works great.
