Practice and reference for electrical apprentices. Things you work at until they stick, and things you look up when you forget them.

Being built

Wiring diagrams you can click through — trace the current, throw the switch, watch the path change
A tape measure drill, to the nearest sixteenth, timed
Trade math practice that marks itself and keeps your streak
Formula sheets sized for a toolbox pocket, free, no email
A glossary in plain words — shrink, gain, take-up, springback

These are teaching materials showing how circuits work. Methods, conductor colours and permitted configurations are set by the Canadian Electrical Code and your local amendments, and electrical work generally needs a permit and a qualified person. Learn from them; don't wire from them.
