          The Commercial Electrician Workbook 
                                by Tom Henry
 
















   
Commercial Wiring
       
This book focuses on the three-phase electrical requirements and distribution for a typical commercial facility, including load requirements, and the calculations necessary to create a successful electrical system.

• Learn how to design electrical sysytems
• Understand grounding and why you ground a system
• Conduit installation and bending
• Plan Reading
• Calculate fault currents
• Three-phase transformer systems
• Alternating current and impedance
• Calculating power factor
• Linear and nonlinear loads
• Harmonics and the neutral

    A power company will sell power to you a little at a time, or all in one huge arc blast. I know that books cost money, but not knowing how or what to do can cost a lot more than just money, even a life.

Work examples: Point to point method of short circuit calculation, Conductor withstand rating, Delta-Wye 3-phase transformer calculations made simple, Commercial buildings (bank, office, restaurant, school, motel, etc.) calculations with demand factors for service sizing, conduit bending, plans reading (restaurant plan in detail), understand why we ground the system, one must understand that under normal conditions the electrical load will function properly whether grounded or not.

Commercial jobs often require you to work with three-phase, higher voltages, metal raceways and heavier equipment, which might bring about a commensurate increase in compensation and pay. This is the book if you want to specialize in commercial. The answer pages are perforated so the class instructor can easily remove them.
