I’m doing a minor remodel to an operating room in a hospital. I have to rework the conduits from the isolation panel to the isolation xfmr (xfmr is located above the isolation panel in the ceiling above the panel). I noticed that there is no bond to the building at the xfmr, just the ground wires with the line and load conductors to the xfmr. It seems like the xfmr chassis should be bonded to the building. Anyone out there with hospital OR experience?
