Gentlemen - Our customer requires a 5hp "Class 1, Div 2, Group B" motor on a compressor system we are supplying but it seems impossible to find such a motor in the US market. Is the CSA designation the same for this motor rating? If we provide a NEC Class 1, Div 1, Group D, T2D are we opening a can of worms for the end users AHJ as to acceptablility? I am inclined to ask the end user to re-evaluate the rating required and if possible, accept the Class 1, Div 1, Group D T2D for the application. Any thoughts would be appreciated. - mrt
