Cheat Sheet
- Three-Phase Power Calculations -
Master the IEEE-standard formula P = √3 × VLL × IL × cos φ for balanced three-phase systems. For example, a 480 V system drawing 30 A at a 0.8 power factor delivers P = √3 × 480 × 30 × 0.8 ≈ 19.95 kW. Use the mnemonic "VIP Cos φ" (Voltage, Current, Power factor) to recall the key parameters.
- Motor Control Circuit Fundamentals -
Review NEMA-rated contactors and thermal overload relays in forward/reverse and star-delta starters to recognize common control schemes. Star-delta starting reduces inrush current to one-third of direct-on-line (DOL) startups, per IEC guidelines. Practice interpreting ladder diagrams to spot coils, NO/NC contacts, and interlock circuits.
- PLC Scan Cycle & Ladder Logic -
Understand the PLC scan cycle - Input scan, Logic solve, and Output update - and how ladder diagrams map real-world devices to contacts and coils. A typical START/STOP rung uses an NO start pushbutton in series with an NC stop pushbutton plus a seal-in contact for hold-in operation. Remember "I-S-O" (Inputs, Solve, Outputs) to sequence the scan process.
- Electrical Safety & Lockout/Tagout (LOTO) -
Follow OSHA 1910.147's five steps - prepare, shutdown, isolate, lock/tag, verify - to achieve a zero-energy state before maintenance. Memorize "Pull Shut Isolate Lock Verify" to ensure no step is missed. Review NIOSH case studies for real-world LOTO examples and best practices.
- Reading Wiring & Single-Line Diagrams -
Differentiate schematic vs wiring vs single-line diagrams: schematics show functional relationships, wiring diagrams detail actual cable runs, and single-line diagrams depict overall power flow. Note terminal numbers (e.g., T1 - T2 for starter coils) and IEC color codes (black L1, brown L2, grey L3). Trace a simple motor starter diagram to sharpen your skills.
