Industrial Electricity and Motor Controls Field Manual (Paperback)

Paperback. When a motor won't start and the fault in front of you doesn't match the diagram in the manual, what do you check first, and why?This field manual is written for industrial electricians, plant maintenance technicians, and advancing apprentices who need more than theory when they're standing at an open panel with a process down. It moves from the electrical fundamentals every industrial technician relies on daily, safety and lockout/tagout, circuit theory, three-phase power, conductor sizing, overcurrent protection and grounding, through motor theory, control circuits, starters, and reduced-voltage starting, into the systems that dominate modern plant floors: variable frequency drives and programmable logic controllers. Every chapter carries the book's Featuring The Fault-to-Fix Decision Path, a four-part reasoning block, Symptom, Likely Cause, Verification Test, Corrective Action, built around the exact judgment call an experienced technician makes when a fault doesn't match the textbook. The book closes with a full Master Index consolidating every Decision Path instance by symptom and by component, turning the manual into a quick-reference a technician can go back to on the job, not just read once and shelve.Inside, You Will FindTwenty chapters covering safety and lockout/tagout, circuit theory, three-phase power, conductors and NEC-based wiring, overcurrent protection and grounding, transformers, AC/DC motor theory, motor nameplate sizing, control circuits and ladder logic, starters and overload protection, reduced-voltage starting, VFD theory and fault diagnostics, PLC architecture and ladder logic programming, and systematic troubleshooting.The Fault-to-Fix Decision Path, a repeated four-part diagnostic reasoning block (Symptom, Likely Cause, Verification Test, Corrective Action) embedded throughout every chapter at the exact points a real fault is likely to occur.A closing Fault-to-Fix Master Index, indexing every Decision Path instance in the book by symptom and by component for fast field lookup.Mandatory Step-by-Step worked examples for every calculation, conductor sizing, overload trip class selection, VFD parameter commissioning, and more, with real inline and displayed mathematical notation, never spelled-out prose or raw formula text.Practical VFD fault code cross-reference guidance organized by underlying drive stage (rectifier, DC bus, inverter) so the reasoning transfers across manufacturers, not just one brand's fault code list.Ladder logic coverage spanning hardwired relay control through PLC-based motor control integration, including forcing, online editing, and safety practice.Full-color and line-art technical figures throughout: schematics, ladder diagrams, wiring diagrams, procedural sequences, and technical photography, drawn from a locked visual inventory matched to the sub-discipline.Currency-flagged code and safety guidance (NEC, OSHA, NFPA 70E) with a clear disclaimer that field values must always be verified against the current adopted code and the equipment nameplate.Keep it on the tool cart, not on a shelf. Whether you're commissioning a new VFD, chasing an intermittent control circuit fault, or mentoring an apprentice through their first lockout/tagout, this manual is built to be reopened on the job, not just read once.
