Does an exam room chair, plugged into a GFCI receptacle, in a Cat 3 healthcare location, having a manufacture installed receptacle that is fed by the chairs isolation auto transformer, creating line to ground 60 volt potential, and within 6’ of a sink a violation of 250.8(B)(5)? If the chairs receptacle is ground fault tested, it does not trip the GFCI the chair is plugged into.
It’s seems the only code provision we can apply is 250.8(B)(5). The chairs manufacturers outlet though technically safe does not seem to meet the requirement and should this receptacle be removed? In Cat 1 and Cat 2 locations GFCI protection can be eliminated due to a tripped GFCI could pose a greater danger to the patient than the shock hazard. So Isolation Power System with monitoring and alarming are utilized. 517.160. the Cat 1&2 provision of no GFCI protection 517.21 does not seem to apply in a Cat 3 location.
Is the exam chairs manufacture’s installed receptacle when within 6’ of a sink in Cat 3 healthcare location in violation, or am I missing something and this can be allowed?
