Overcurrent Protection I – Short Circuit Calculations

This course reviews the principles of electric systems during faulted conditions and how short circuit currents are calculated in both three-phase and single-phase systems. After taking this course you will: Understand the NEC requirements for equipment protection Understand what short circuit currents are and the impact on circuits Know how to calculate short circuit currents using the per-unit method Know how to calculate short circuit currents in both three-phase and single-phase applications. This course includes a multiple-choice quiz to test your understanding of the material.
