Scope:

1.1

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.

1.2

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.

Project need:

To detect and mitigate the effects of arcing faults that can pose a risk of fire ignition under certain conditions if the arcing persists.
