Practical Drawing in AutoCAD
An interactive, hands-on module introducing AutoCAD (Electrical) for creating accurate and standards‑compliant electrical drawings in both substation and building services contexts. Participants will learn professional techniques for drafting schematics, layouts, wiring diagrams, and annotated outputs ready for construction and documentation.

Design Review With AuthCAD
This essential capstone module enables participants to refine their electrical design outputs through structured peer review, instructor assessment, and checklist-based quality control. Participants submit their AutoCAD or BIM drawings—from lighting layouts and cabling plans to panel diagrams—and receive qualitative and compliant feedback aligned with real-world engineering standards.

Dimension Analysis
This essential module teaches how to evaluate and verify all physical dimensions in electrical design—ranging from cable sizing and fault-level inputs to safe space clearances, riser alignment, and equipment layout. You'll learn accurate dimensioning to ensure compliant, maintainable, and efficient electrical installations.

Conduit Sizing Calculation
This module equips learners with the skills to select correctly sized conduits for electrical systems based on valid code methodologies and installation best practices. You’ll master how to calculate conduit fill, prevent jamming, comply with NEC and IEC standards, and justify conduit choices in design documentation.

Cable Sizing Calculation
You’ll learn to determine appropriate conductor cross-sectional areas (c.s.a.) through a systematic process that balances ampacity, voltage drop, and short-circuit withstand capacity. Criteria include expected load, installation conditions, grouped cable derates, ambient temperature, voltage regulation, and mechanical safety.
