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