From the author of Pocket Guide to Residential Electrical Installations and the source of the National Electrical Code comes this portable compendium of useful on-the-job data: calculations, formulas, tables, NEC(R) rules, and hands-on techniques. Features include calculations for transformers, motors, and voltage drop; grounding and bonding requirements, wire and electrode sizing, and load calculations; extensive material on Ohm's Law, knots, crane signals, and first aid procedures; and an illustrated guide to conduit-bending measurements and techniques.
