Overview

The Canadian Electrical Code is published in several parts, with Part III standards covering electrical protection, safety, and design criteria related to both overhead and underground systems for distribution and transmission. ‘Overhead Systems’ refers to the lines and equipment associated with overhead electrical supply and communications systems located entirely outside buildings and fenced supply stations. The tenth edition of CSA C22.3 No. 1 Overhead Systems is one of a series of standards issued under the Canadian Electrical Code, Part III.

 

Highlights of C22.3 No.1

• Removal of the linear design method, completing an updating process that was initiated in 2003

• New definitions and terminology including ‘pole brace’, ‘rated tensile strength’ and ‘vegetation control cycle’

• Revised definitions including ‘vegetation management’ and ‘communications drop’

• Revision of load factors for guy assembles to reflect the transition to the non-linear method of analysis

Project need:

To review the Standard within the required 5 year period.
