What will I learn?
The Protection and Selectivity Course equips you with practical skills to assess short-circuit levels, select appropriate 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 strategy, and confirm coordination through on-site tests, labelling, and documentation to ensure reliable and compliant electrical systems.
