June 26, 2013 – The Electrical Black Book presents information on electricity in a small pocket-book format. Pat Rapp, author of the book, wanted to condense formulae, tables, calculations and more into the small book. It contains information on electrical safety, electrical laws and formulae, calculations and conversions, and more, but does not claim to be a substitute for the National Electrical Code. Rapp has been involved with the engineering and electrical supply, fastener and cutting tool industry for the past 30 years and has gained a knowledge of the industry’s day-to-day questions.
