Electrical Design for Industrial, Commercial and Institutional Facilities

After participating in this course, you will be able to do the following:

• Apply electrical design concepts in your work situations
• Design electrical systems in compliance with the Canadian Electrical Code
• Determine load characteristics and demand factors of your system
• Analyze fault currents in AC systems as well as in distribution equipment
• Increase the efficiency of your substation

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