What will I learn?
The Protection and Selectivity Course gives you practical skills to analyze short-circuit levels, choose correct breaking capacities, and build clear one-line diagrams for small commercial installations. Learn how to select and coordinate MCCBs, MCBs, RCDs, and RCBOs, apply proper trip curves, design an effective RCD strategy, and verify coordination on-site with essential tests, labeling, and documentation for reliable, compliant systems.
