Transfer Panel (60A/60A), Briidea Transfer Switch for Portable Generators 15,000 Watts, Manual Transfer Switch Kit, Prewired and Sixteen Pre-Reserving Holes for Easy Installation

First thing to point out: This IS an isolation transfer switch. It allows switching between two incoming power sources to a common load. In other words, the reviews on this product complaining about having to still turn the main breaker off means they incorrectly wired their switch. When wired properly this will allow switching between utility power and generator power without having to switch any other breakers on or off. This is not a product that should be installed by people who do not have a solid concept of how electrical systems work.I received a used item that had "Defective" written in permanent ink on the face of the box and had holes drilled all over the box. There was nothing defective about the product, and sadly I could not use it due to all of the holes drilled in the box. Based on the reviews of this product, I suspect the one I received was returned by someone who had no knowledge of how to properly install the product.For the price and application, this is a fantastic product and does exactly what a transfer switch is supposed to do. My only recommendation is thoroughly inspect the product you receive to make sure it wasn't a returned item from someone else.

Thought this would be: power to house-off, power from genny-on. But nope. It's just a switch. We still have to turn the main breaker off before using this thing to switch to genny. Which could have just as easily been done with a dedicated breaker in the breaker box at the savings of about $100. So if you want a smanzy fancy switch this is your product. Otherwise don't be a dummy like me, and just use an existing breaker.

Perfect for my generator hookup
