Anytime I was in a panel like that it was old as dirt and those labels fall of and asking for a schematic is a joke.Nope, these wrap all the way around the wire, and they're not paper. Plus we provide a wiring schematic with all of our tools. If you sit down and study our schematics, they use ladder logic, pretty easy to follow once you get used to them. Once you understand how we wire them, you don't even really need a schematic.
