To be honest I'm not an Electrician I'm not even sure what half this stuff is for. I just wanted it for the bag, the zip ties, and the locks. I thought it wasn't a bad deal for 20 dollars. We have 3 gates and a shed we needed locks for and we needed zip ties for our signs No Trespassing, Beware of dogs, No solicitation, Video surveillance, Keep the gates closed, etc.
