Decades ago I knew very little about electrical wiring but I had one of those yellow Reader's Digest Home improvement books and referred to it on many occasions from wiring two switches to one light, 220 wiring for a compressor etc. Gradually it's been fun and Ive never been shocked-at least by electricity since age 11. I wired an entire house a decade ago and Never had any problems at all except one time I failed to twist the connecting wires and had no power to an outlet until I figured it out. So don't be a "no wire twister."
