Keeping the power flowing to life support systems and equipment used during patient procedures is vital to continuity of care. However, disruptions to a facility’s “supporting systems” can also have a significant impact on patient safety and healthcare outcomes. Choosing the right electrical components can literally save lives. 

High-voltage solar presents an emerging opportunity for electrical OEMs serving utilities and the industrial community. By supplying systems able to withstand the requirements of 2000 VDC (and higher) solar arrays, OEMs are paving the way for the sustainable, commercial viability of industrial and utility-grade solar. 

For electrical OEMs, understanding UL 891 and UL 67 is vital for safe switchboard and panelboard designs. This article offers a practical overview of their differences and applications, focusing on compliance and innovation.
