on site we have 4 motors (siemens) with the following statement stamped on them,
"motor meets during normal operation the definition in the national electric code (2005)-501-125 (B) for motors to be installed in Class 1 Div 2 areas"
these motors are equipped with Thermistor protection, my question is, does the thermistor protection have to be hooked up to the switchgear to trip, for the motors to comply with code requirements ?
