Course Description

Designers, installers and operators of electrical equipment and electrical facilities are responsible for code compliance and public safety. The Canadian Electrical Code provides minimum safety requirements designed to prevent undue electrical fire and shock hazards. This seminar offers important insight into correct application of the code to wiring systems, grounding and bonding, protection and control, motor applications, lines, high voltage substations, hazardous locations, fire alarm systems and emergency systems. It explains the use of other standards referenced throughout the electrical code such as the National Building Code, IEEE, NFPA and CSA are covered as applicable.

The seminar will highlight important changes; some examples:

  • Many familiar terminologies have been redefined for more clarity and to better align with other codes and standards
  • The rules of Section 10, Grounding and Bonding have been completely re-organized along with important revisions
  • Rules previously found in Section 4, Conductors have been moved to Section 12, Wiring Methods
  • The number of connections between the grounded service conductor (neutral) and ground have been reduced to one, leading to new wiring methods
  • New types of equipment, materials and technology are introduced along with applicable rules
  • Tamper-resistant receptacles in areas where children may be present
  • Ground fault circuit interrupters for electric heating devices and controls

Participants should bring a copy of the 2018 Canadian Electrical Code to the course as it will be frequently referenced throughout the two days.

You Will Receive

Each participant will receive a set of notes that will serve as reference and information.

Who Should Attend

This seminar will be of interest to engineers, technologists, contractors and management involving design, construction, maintenance, plant management, electrical utility operations, manufacturing and government.

Course Objectives

Electrical code compliance is a mandatory requirement in all provinces and territories of Canada. Up-to-date electrical code knowledge is fundamental to accurate specification, installation and operation of electrical equipment and facilities. Compliance is a legal requirement. This seminar offers participants a comprehensive understanding of the code in a broad range of its application.
