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