Preface 

This is the second edition of CSA C22.2 No. 330, Photovoltaic rapid shutdown systems , one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. It supersedes the previous edition published in 2017. This Standard sets out provisions for photovoltaic (PV) rapid shutdown systems and is intended to be used in conjunction with CSA C22.2 No. 107.1. PV rapid shutdown equipment is designed to protect emergency personnel by limiting the conductors it controls to not more than 30 V dc or 15 V ac (rms), 8 A and 240 V•A. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was prepared by the Subcommittee on Photovoltaic Rapid Shutdown Systems, under the jurisdiction of the Technical Committee on Industrial Products and the Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. 

Scope 

1.1 This Standard specifies requirements for photovoltaic (PV) rapid shutdown systems (PVRSS) and PV rapid shutdown equipment (PVRSE) intended to be used in locations in accordance with CSA C22.1, Canadian Electrical Code, Part I (CE Code, Part I) and rated 1500 V or less. A PVRSS is an integrated set of discrete PVRSE that work together to shut down one or more PV arrays installed on a building or structure. 

1.2 In this Standard, “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 (non-mandatory) to define their application.
