Current & Compliant: Navigating the Ontario Electrical Code

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

• Employ the requirements of the code to ensure they are accounted for in the design, construction and operation of electrical systems
• Use your knowledge of grounding and bonding requirements in the code
• Better protect your electrical system with the additional insight gained into the protection and control requirements of the Code
• Upgrade your compliance with the requirements for hazardous locations in the Code
• Work with the code having understood the requirements about motor applications, substations and high voltage lines requirements in the code
• Comply with the Code requirements for workplace electrical safety
• Understand the Shock and Arc Flash Hazards associated with installations

Description
Electrical safety is the responsibility of designers, installers, and users. The code establishes safety standards for the design, installation, maintenance, and use of electrical facilities to prevent undue electrical arc flash, fire, and shock hazards.

Excellent code knowledge is a prerequisite to correct specification and application of equipment and wiring in all areas of design, construction, maintenance, manufacturing and the use of electricity. This course demonstrates accurate interpretations and applications in areas such as wiring systems, grounding and bonding, protection and control, motors, lines and substations, explosion-proof areas, fire alarms and emergency systems.

It also highlights other key standards, including the Building Code, IEEE, NFPA and CSA, which are referenced throughout the code.

Who Should Attend
This course will be of interest to Engineers & Others in Design & Construction • Engineers & Other Plant Personnel • Maintenance & Safety Personnel • Contractors • Fire & Accident Investigators • Operating Personnel • Manufacturing, Government & Electrical Utility Staff
