I have a control station that just has two selector switches on it in a Class 1 Div 2 Area. I'm providing for this control station a Stainless Steel Nema 4X enclosure and a Cutler and Hammer Selector switch that is rated for Class 1 Div 2 area. The Selector switch contacts are Hermetically Sealed.
My specification is calling for a Nema 4x and Nema 7 enclosure. Do I have a case to state that a Nema 4X enclosure with the hemertically sealed contacts does not need a Nema 7 enclosure rating?
