Hello! On a data sheet we specified a pump manufacturer and model number. In addition, the data sheet has other process information, ie. specific gravity, viscosity, design flow rate, power supply, etc. We also specified the Area Class to be Class 1 Div 2 Group B.
When we look up the pump information on the manufacturers website it says it's, "Class 1, Group C&D". I assume they mean Class 1 Div 1 or Div 2 Groups C&D.
1) Does "Class 1, Group C&D" envelope both Div 1 and Div 2?
2) Will a Class 1, Group C&D rated pump/motor be code compliant when a Class 1, Div 2 Group B was specified?
I have read Article 500 and 501 (2008 edition) and it sounds like if it's Div 2 then even though Group B was specified, a Group C or D could be used. I'm just not sure I'm interpreting the Code correctly. What section of the Code has the answer?
I really appreciate the help! Thanks in advance!
