What will I learn?
This short, practical Electrical Protection and Selectivity Course equips you with skills to size and set protective devices, calculate fault currents, and use coordination methods for low-voltage systems. You'll learn to interpret and apply time-current curves, select MCCBs, MCBs, fuses, and motor safeguards, manage arc flash and shock hazards, and produce straightforward reports that boost safety, dependability, and cut down on unnecessary interruptions.
