Preface:

This is the first edition of CSA C22.2 No. 271, Photovoltaic cables, one of a series of Standards issued by the Canadian Standards Association under Part II of the Canadian Electrical Code.

Scope:

1.1
This Standard specifies requirements for photovoltaic single-conductor and multi-conductor thermoset-insulated wires and cables that are rated 600, 1000, or 2000 V, suitable for ac and dc systems, and intended for installation in accordance with the Canadian Electrical Code, Part I.

Notes:
(1) See Table 1 for the wire and cable types covered by this Standard.
(2) See Table 2 for voltage and maximum conductor temperature ratings for the wire and cable types covered by this Standard.

1.2
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; and "may" is used to express an option or that which is permissible within the limits of the standard. 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 (nonmandatory) to define their application.

1.3
The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only. See more
