What will I learn?

The Protection and Selectivity Course provides 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 proper trip curves, design an effective RCD strategy, and verify coordination on-site with essential tests, labelling, and documentation for reliable, compliant systems.

Elevify advantages

Develop skills

  • Short-circuit calculation: estimate fault currents and choose safe breaking capacity.
  • One-line diagrams: draw, read and optimise small commercial power distributions.
  • Protective device selection: match MCCB, MCB, RCD, RCBO and fuses to real loads.
  • Selectivity tuning: set TCCs to avoid nuisance trips and protect critical circuits.
  • RCD strategy: place, rate and coordinate RCDs/RCBOs for people and equipment.
