Pat,
Whenever I see a post regarding GFIs, I always reply with the same advice. Have the hospital change out their GFIs with ones that meet the latest requirements, which in the US is the 2006 versions. Older GFIs were very susceptible to RF noise and was prone to false tripping. We have had numerous customers complain about our products tripping their GFIs. We change out their GFIs with the 2006 versions and the problem goes away every time. Good luck.

Specifically, the GFI/RCCB/RCD (ground fault detector) installed in the operating room trips, shutting off power to the system. After resetting the GFI, the equipment can be started successfully. My question concerns the use of GFIs in operating rooms. This sounds unusual to me, and I'd think the GFI would have to meet many of the same requirements that medical equipment needs to meet (e.g., IEC60601-1 approval). Is anyone familiar with either requirements or prohibitions on the use of GFIs in an operating room?
