Preface:

This is the first edition of CSA C68.8, Overhead aluminum secondary and service-entrance cables and conductors for electrical distribution utilities.

Scope:

1.1
This Standard specifies requirements for overhead secondary and service-entrance cables and conductors intended primarily for operation by electrical utilities.
Note: The operation of cables and conductors complying with this Standard by other than an electrical utility can be subject to additional requirements by an authority having jurisdiction.

1.2
The cables and conductors covered by this Standard are intended for overhead installation and for operation at normal maximum conductor temperatures of 75 °C and 90 °C. Provision is made for assembly of multiple conductors. Single 600 V insulated conductors are intended for field-spun applications.

1.3
In CSA Standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
