What will I learn?
This short, practical Electrical Protection and Selectivity Course equips you with the skills to size and set protective devices, estimate fault currents, and apply coordination techniques for low-voltage installations. Learn to read and use time-current curves, choose MCCBs, MCBs, fuses, and motor protection, address arc flash and shock risks, and prepare clear reports that enhance safety, reliability, and minimise nuisance trips.
