2024 Canadian Electrical Code - Section 8
Circuit loading and demand factors – Online Training
Product Details
Course Overview
This course is part of the CSA Group Modular Online Training Program. This online course provides an overview of Section 8 in the 2024 Canadian Electrical Code, Part I. Rather than reviewing the Code in its entirety, this course is designed to provide an overview of Section 8 of the CE Code.
Section 8 is a general Section of the Code that provides requirements for the ampere rating of services, feeders, and branch circuits based on the calculated loads connected to these services, feeders, or branch circuits.
Section 8 deals with a variety of situations and environments, and assigns demand factors to certain loads, recognizing that, in practice, circuits, feeders, and services are not likely to attain maximum loading at the same time, as some loads (e.g., electric heating and air conditioning, etc.) do not operate in a building at the same time. Some types of loads are dealt with in other Sections, such as Section 28 for motors, Section 42 for welders, and Section 62 for electric space and surface heating.
This Section covers conductor ampacities and equipment ratings required for consumer’s services, feeders, and branch circuits, and demand factors and continuous and non-continuous loads.
A certificate of achievement is provided upon completion of the course.
For nearly 90 years, the Canadian Electrical Code, Part I has been and continues to be a comprehensive model Code that provides guidance to help make electrical installations and equipment safer.
Learning Objectives
After taking this course, you will be able to:
- Interpret and apply the Section 8 requirements for voltage drop.
- Differentiate between continuous and non-continuous loads, and how they affect circuit loading.
- Size conductors and determine the rating of an overcurrent device based on the circuit loading requirements of Section 8.
- Apply the appropriate demand factors to the requirements of Section 8.
- Determine the calculated load for feeder and service conductors supplying various occupancies and buildings.
- Describe the demand requirements for heater receptacles.
Target Audience
All professionals, apprentices and students in the electrical industry.
