Taschenbuch. Etat : Neu. Neuware - When The Line Goes Down, Guesswork Gets ExpensiveThe motor will not start. The overload keeps tripping. Production is stopped, and everyone in the plant is looking at you.Most books leave you stranded at exactly this moment. They give theory without the arithmetic, or procedures without the reasoning behind them. So you swap parts, hope something works, and learn nothing you can use on the next fault.A Guide That Shows Its WorkFive parts and twenty-one chapters take you from safe isolation to a running drive, and every step is checkable. Calculations are worked in full with units tracked. Code requirements are identified by article so you can verify them yourself. Worked examples, practice problems, key terms and reference tables run throughout.What You Will Be Able To Do- Make equipment safe before you touch it, and verify it rather than assume it- Read an incident-energy warning label and select protection that matches the real exposure- Size conductors, protective devices and overload protection for a complete motor branch circuit- Decode a motor nameplate and match it to torque behaviour, design characteristics and load- Trace ladder logic, seal-in circuits, interlocks and multiple control stations, and find the break- Choose a starting method that suits the load, and apply speed control where it genuinely fits- Work a fault from reported symptom to root cause with a repeatable, instrument-based methodCoverage At A GlanceHazard control and safe isolation; current, voltage, resistance and power; direct and alternating current behaviour; magnetism and induction; three-phase systems; conductors, insulation and ampacity; voltage drop; wiring methods and enclosure ratings; overcurrent protection; grounding and bonding; fault current and coordination; motor types and nameplates; motor circuit sizing; control devices and ladder diagrams; starting methods; controllers and ladder logic; adjustable-speed drives; test instruments and systematic fault-finding.Written For>Build the understanding that holds up when the panel is live and the plant is waiting. Get your copy, work the examples with a calculator in hand, and start troubleshooting with reasons instead of guesses. N° de réf. du vendeur 9798192987667
