2015 Canadian Electrical Code

October 26-27, 2017 - Halifax, NS
Register Here


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. Provincial and Territorial amendments to the code are also covered as applicable.

The seminar will highlight some important code changes such as new definitions and new requirements for grounding and bonding, tamper-proof receptacles, sunlight resistance for wiring and cables, abandoned wire and cables, carbon dioxide detectors, wiring over swimming pools, hazardous location motors transformer loading and overcurrent protection coordination for emergency power supplies.

Participants are encouraged to bring a copy of the 2015 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. Excellent code knowledge is fundamental to correct specification, installation and operation of electrical equipment and facilities. Compliance with the electrical code is a legal requirement. This seminar offers participants an in-depth understanding of the code in a broad range of applications.


Day 1 - registration/check-in will start at 8:00 a.m. with sessions to begin at 8:30 a.m. and adjourn at 4:00 p.m. Day 2 will commence at 8:30 a.m. and adjourn at 4:00 p.m. There will be 15 minute mid-morning and afternoon breaks. Lunch is on your own from 12:00 noon to 1:00 p.m.
