Conduit bending one page at a time: the hand bender and its marks, take-up and stub-ups, back-to-back bends, offsets with multipliers and shrink, 3- and 4-point saddles, kicks, and fixing a dog leg.

Motors and controls one page at a time: the nameplate, the full-load current tables, conductors, short-circuit and overload protection, disconnects, magnetic starters, start-stop circuits, forward-reverse, reading a ladder diagram and troubleshooting.

Transformers one page at a time: how they work, turns ratio, kVA and current, single-phase and three-phase connections, delta and wye, buck-boost, Article 450 overcurrent protection, grounding a separately derived system, and worked sizing problems.
