ULSE Publishes Safety Standard for Photovoltaic Hazard Control

On December 10, 2020, UL Standards & Engagement published ANSI/CAN/UL 3741, Standard for Safety for Photovoltaic Hazard Control. The Standard is specifically intended to establish and expand requirements to help keep firefighters out of hazardous current paths when responding to emergency situations in homes and buildings with PV systems. Systems that comply with UL 3741 should also decrease potential hazards for others working in and around the PV array.
