NEC certification on its own is not sufficient. You are correct, the equipment specified is flameproof similar to Class1 Div 1 Gas Group C = Hydrogen and T4=135C EExd = flameproof suffix e = increased safety (probably the terminal box) This classification is common for a motor in a Zone 1 area For more info see: http://www.rstahl.com/ http://europa.eu.int/comm/enterprise/atex/index.htm http://www.ceag.de/ Regards Sean Upvote 0 Downvote
