I usually have no use for table of contents, but this one tells a lot about this book. It all starts off with DC Electricity 101, a section that includes an easy to understand basic description of what the smoke is doing before you let it out of the wires. The section also includes some charts to help you pick wire size, some simple wiring diagrams, and fuse descriptions with where and when to use different fuses. It also talks about relays, solenoids, and circuit breakers. Basically it is safety first with some added info you could use at home or in the field.
