Class II, Div 2, Group G Instrumentation Requirments
Class II, Div 2, Group G Instrumentation Requirments
(OP)
Does IP67 rated instruments meet the requirments for a Class II, Div 2, Group G area. The Nema rating for this type of area clasification is Nema 9 which is for indoor use. The area I'm working with in is under a canopy, but is possibly exposed to windblown rain, which ordinarily require Nema 4 instruments for protection against water. There doesn't seem to be a suitable Nema rating for this type of area classification in an outdoor environment
