Description
This course focuses on basic electrical design concepts and provides an understanding of the methods used to design low-voltage power distribution systems. A practical approach is taken to discussing low and high-voltage electrical circuits, equipment, and systems used in facilities. The course emphasizes the Canadian Electrical Code while teaching the fundamentals of electrical generation, transmission and distribution, design philosophy and procedures, construction materials, services, grounding, and power quality.

The course will prepare you to review electrical systems for compliance with the Canadian Electrical Code. No electrical design experience is required. All topics begin at the fundamentals level.
