I dont know much beyond basic 120 other than big picture theory, at least as far as house wiring goes. Complex circuitry on AC isn't my jazz. I can map and build a wiring harness for your custom built racecar though. I can build an antenna for broadcast (and did from 3 leg sub-pump wiring by removing most of the middle wire and making a ladder-line, portable, flexible, 2M and 440 transmit antenna). Hell, in the right toy shop I could build a tunable radio. But I only know enough about designing house systems to burn my house down or shock my wife every time she turns the light on in a totally different room, and a resource like this would be helpful... If only it wasn't written in Canadian.

Jokes aside, I'll have to pick one of these up next time I'm at the project big box. Thanks!
