What will I learn?
The Protection and Selectivity Course equips you with hands-on skills to assess short-circuit levels, pick the right breaking capacities, and create straightforward one-line diagrams for small commercial setups. You will learn to choose and coordinate MCCBs, MCBs, RCDs, and RCBOs, apply suitable trip curves, develop an effective RCD plan, and confirm coordination on-site through key tests, labelling, and records for dependable, compliant systems.
