THE Industrial ELECTRICITY and Motor CONTROLS HANDBOOK: From Relays Contactors to PLCs VFDs — Practical Wiring, Sizing, Fault-Finding for Technicians

Master industrial electricity and motor controls from the fundamentals to modern automation.The Industrial Electricity and Motor Controls Handbook is a practical reference for electricians, maintenance technicians, apprentices, trade students, and controls professionals who need to understand how industrial electrical systems work, how motor control circuits operate, and how to diagnose faults systematically.Instead of teaching you to memorize wiring diagrams, this handbook builds the electrical knowledge needed to understand why each circuit behaves the way it does. You will progress from electrical safety and core circuit theory through three phase power, motors, control devices, variable frequency drives, PLCs, and industrial troubleshooting.Inside, you will learn how to: - Apply essential electrical safety principles, including NFPA 70E practices and lockout/tagout procedures- Work confidently with voltage, current, resistance, power, AC circuits, and three phase systems- Select and use electrical test instruments for industrial troubleshooting- Understand conductors, raceways, grounding, and industrial power distribution- Understand induction motors, single phase motors, DC motors, and specialty motors- Read motor nameplates and work through practical NEC Article 430 motor circuit calculations- Read and interpret electrical symbols and ladder diagrams- Understand relays, contactors, overloads, timers, switches, sensors, and control devices- Analyze start stop circuits, reversing circuits, interlocking, and motor starting systems- Understand reduced voltage starters and solid state starting methods- Size and apply motor protection and overload devices- Understand variable frequency drives, their operating principles, setup considerations, and common faults- Understand programmable logic controllers, PLC logic, I/O, and industrial automation- Diagnose electrical and motor control problems using a structured troubleshooting process- Build an effective preventive maintenance approach for industrial electrical equipmentThe handbook follows U.S. industrial electrical practice and references the National Electrical Code, NFPA 70E, NFPA 79, NEMA, UL, OSHA, and related standards where appropriate. Your manuscript also provides U.S. customary and SI units.Each chapter combines technical explanation with worked numerical examples, practice problems, worked answers, and key relationships, making the book suitable both for structured study and as an on the job reference.Whether you are preparing for industrial electrical work, strengthening your motor control knowledge, moving into maintenance and automation, or looking for a dependable reference for the plant floor, this handbook gives you a structured path from electrical fundamentals to modern industrial controls.Build the knowledge to read the circuit, understand the equipment, trace the fault, and work through industrial electrical problems systematically.
