Quick & Basic House Wiring: An Easy Guide to the Electrical Wiring Inside Your Walls (Practical-Is-Good (P.I.G.) Technical Training)

This quick and fun book tells you what the wiring looks like inside your walls. Ever wonder why the switches at the bottom and top of a stairway are called 3-way when there are only two of them? How about the puzzle of why a 2-wire cable has three wires and a 3-wire cable has four wires? This book explains it all. It also tells why your house is wired in parallel, not in series, and that every circuit is made up of a power supply, a switch, and a load.
