What you will be able to do

  • Size motor branch circuit conductors and protection from nameplate data
  • Explain starting current behaviour and its effect on system voltage
  • Describe transformer loading, regulation, and losses
  • Read a vector group designation and say what it implies for paralleling

Prerequisites

  • Electrical Foundations

What counts as complete

All four modules marked complete with checks and reflections recorded.

Opening a lab never marks a module complete on its own.
