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 rules, and hands-on techniques.  Sized to fit pockets and toolkits, this streamlined electrical resource includes everything from important mathematical formulas to frequently used 2005 NEC tables.  Charles Miller compiled and organized the data electrical professionals need most in the field:

• Wiring configurations for three and four-way lighting switches, as well as for phone and data jacks.
• A thorough chapter on conduit bending including helpful drawings.
• Voltage drop calculations, conduit and tubing fill tables, conductor sizing information, and load calculations.
• Clear explanations of calculations based on Ohm's Law.
• Easy-to-follow first aid procedures.
