If we ever wanted to put a product in a Class 1 Div 1 or 2 Group D area and wanted to use a stainless tube instead of rigid metal conduit for a raceway... is this allowed?
I assume you have to use a rigid metal conduit, but our normal product which houses the wire for a sensor that is screwed on the end uses a 316 stainless tubing that holds up well for heat....
And not that anyone should know this off the top of their heads, but if you run a flex conduit approved for c1 div2 grp D to a nema 7 box... does there have to be a seal on the end of the conduit? or does a nema 7 box have some sort of built in seal already....
