Electrical reference book from Summit Electric Supply, updated for the 2002 National Electrical Code. The book contains information on wiring, formulas, diagrams, symbols, hp ratings, Ohm's Law, conductors, power factor, transformers, lighting, motor data, NEC tables, NEMA, ampacity, and voltage drop. The book is well used, but appears to have all the pages. Pages are a little roughed up and the cover page is loose. See all images
