Great price on this well made transfer box. Installation was fairly simple but not easy as I had to drill through brick and route a power wire through my attic and down an inside wall into the closet where my breaker box is located. Yours may be easier to access. You will need some 10/3 with ground or larger wire to connect to the generator input box. If you cannot use a mechanical lockout, then this is what you need to make a safe and legal generator hookup. If you are not comfortable with the installation you should get a professional to install it for you. Still need to trim out box in photo.

Great unit heavy duty box that locks. My son is electrician said this is one of the best he has installed. I read the manual I'm sure i could have installed it myself.instructions were good. Wires were labeled which you can slide up by breakers

bought this thought it was a great deal hooked it up and tested worked great. Had my first power outage tonight 2 circuits fried after 3 hours had to open up breaker box and disconnect it to get voltage after power came back on. Do not buy this piece of junk

The product description says 'PreWired,' but the wiring was a complete mess—no clear labels or proper instructions. The manual had vague diagrams, and the NEMA L14-30p inlet compatibility was not well explained. As a DIYer, I spent hours trying to figure it out, and even then, I wasn’t sure if I connected it correctly. Amazon should require sellers to provide proper installation guides or videos.
