Draft Scope/Description:

1 Scope


This standard applies to DC arc fault protective devices (DC-AFPDs) and devices incorporating arc fault circuit protection intended for use in direct current circuits in photovoltaic (PV) systems having a maximum voltage rating of 1000V dc.


This standard contains construction, test and marking requirements for DC-AFPDs and is designed to be used in conjunction with CSA Standards CAN/CSA-C22.2 No. 5, CAN/CSA-C22.2 No. 144.1, C22.2 No. 304, and C22.2 No. 107.1 as applicable.


A DC-AFPD is intended to detect and mitigate the effects of arcing faults that can pose a risk of fire ignition under certain conditions if the arcing persists.  A DC-AFPD is not intended to detect glowing connections.


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.
