SUMMARY OF TOPICS

The following new UL Standard is being proposed for preliminary review and comment only:

1. For Preliminary Review Only: The proposed first edition of the Standard for Photovoltaic Hazard Control, UL 3741, including applicable requirements for Canada. Fire fighters performing operations involving buildings with attached Photovoltaic (PV) arrays may be exposed to electrical hazards from damaged PV equipment. These requirements for PV Hazard Control components, equipment and systems provide a reduced level of shock hazard from energized PV system equipment and circuits located within the PV array after the operation of any required hazard control initiation function.
