Class 1 Division 1 motor and space heaters

Class 1 Division 1 motor and space heaters


My motor supplier informed me that anti condensation heaters are not available for Class 1 Division 1 motors.
The client specified space heaters for all motors.
I went through the NEC NFPA 70 Article 500 but they only mention space heaters for Class 1 Division 2 motors however there is no mention that space heaters can not be used in Class 1 Division 1 motors.
Could someone confirm that the anti condensation heaters cannot be used in Class 1 Division 1 motors and if possible, give me a reference to show my client.

Thank you.

Phone a couple of other suppliers and ask for suggestions.
