Isolated Power Systems

for Healthcare Facilities


Standards such as NFPA® 99 and CSA Z32 require isolated power systems or GFCI's in all areas deemed "wet procedure locations" in healthcare facilities.  BENDER Isolated power systems offer an invaluable advantage compared to GFCI's - early detection of ground faults allows for critical systems to remain online in a single fault condition.  BENDER isolated power panels provide isolated power to electrical systems in operating rooms and other critical care areas.  Utilizing the latest in technology, BENDER equipment ensures that electrical ground faults are detected and located fast and automatically, in compliance with the latest standards and code requirements. 

BENDER isolated power panels for healthcare facilities conform to: NFPA® 99, NFPA® 70(NEC®), UL 1047, UL 1022, UL 50, CSA Z32, RETIE and AEA 90364-7-710.
