Sparky,
If you are installing explosion proof equipment in a Div 2 area you are losing a lot of money. The seal is permitted on either side of the boundary, so in this case it must be inside the pump as it is not outside(of course that would assume that a seal was actually installed as required). I work at a chemical plant and if my electricians are installing explosion proof fittings in the Div 2 areas, I'll soon go broke. In this case the area in question is Div 2 and there is no requirement to install explosion proof fittings in a Div 2 area. Your reference to 501-5(c) applies to the seals only. The wiring methods are in 501-4(a) for Div 1 and 501-4(b) for Div 2.
