[DonRotolo]

Also get into the stuff they need to do:

Wire stripping theory (don't nick the strands, strip length is important, twist stranded wire ends to avoid stray strands)

Wire colors that are legal. (In fact, have them read some parts of last year's electrical rules, making sure they understand that these are LAST YEAR's and not valid for 2014)

Wire gauge and current capacity

Crimping tools, techniques, and terminals (and what the colors on the terminals mean...)

Screw torque (and where to find the specification!)

Wire dress (keeping wires neat - how and why)

Zip ties and the right way to cut the ends off (no sharp ends)

Insulation and chafing (e.g., against a metal edge)

The danger of electricity and batteries (high current generates heat, wires and batteries can explode, etc.) (warm connections and wires are damaged connections and wires)

Safely carrying a battery.

(the above are some of the more importat of my peeves)
