Course Overview

This online, self-guided course is designed to help electrical professionals understand and apply the requirements of CSA C22.1:24, Canadian Electrical Code, Part I for designing, planning, installing, inspecting, or maintaining electrical work and electrical equipment in occupancies.

Included in this course:

• Sections 0-16 and 26, which are the general sections of the Code
• Sections 26-32 and 46

With a focus on new installation and renovation projects, this course explores practical Code concepts through scenarios, interactive activities, and real-world examples for buildings, structures and premises within the Code’s Scope. Adhering to Code requirements helps to create and maintain a safe working environment for people and places, during installation, when in use, and for maintenance.

Completed online, you can take between 15 minutes or 12 hours of training at any time. Only learn about topics you need for your job. The modules vary in length, from 25 to 90 minutes. Each includes a quiz, with an unlimited number of attempts, to test your knowledge and understanding of the course’s subject. After completing each module and passing the quiz, you earn a Certificate of Completion.

This training is developed with input from a broad cross-section of electrical industry experts and with cooperation from all provinces, territories and several key jurisdictions across Canada.

Jurisdictions across Canada adopt the Code as a model code for regulation either in its entirety or with provincial or territorial interpretations. The Code is an integral part of the Canadian Electrical Safety System.

Learning Objectives

At the end of this course, learners will be able to:

• Locate definitions in, restate the Objective of and recognize the overall Scope of the Code as they apply to electrical work and electrical equipment in specific electrical installations.
