I am an electrician for a small 250 bed hospital.I should say I am thee electrician for the hospital.Anyway we built a new facility 3 years ago.each O.R. suite has its own 120/208V 3 phase panelboard.There is no ground isolation, line isloation monitors or gfcis in the rooms.The rooms are anything but a dry location.The way I understand the code you must have gfcis and if you can't tolerate nuisance tripping you must have a ground isloation panel.Any clarity will help.
