CSA C22.2 NO. 62790:20

Preface:

This is the first edition of CSA C22.2 No. 62790, Junction boxes for photovoltaic modules — Safety requirements and tests, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 62790 (first edition, 2014-11). It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code.

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:

This International Standard describes safety requirements, constructional requirements and tests for junction boxes up to 1 500 V dc for use on photovoltaic modules according to class II of IEC 61140:2001.

This standard applies also to enclosures mounted on PV-modules containing electronic circuits for converting, controlling, monitoring or similar operations. Additional requirements concerning the relevant operations are applied under consideration of the environmental conditions of the PV-modules. This standard does not apply to the electronic circuits of these devices, for which other IEC-standards apply.

NOTE For junction boxes according to classes 0 and III of IEC 61140:2001, in photovoltaic-systems, this standard can be used as a guideline.
