Single phase 1/2 hp motor Class I Div II Groups B, C, D
Single phase 1/2 hp motor Class I Div II Groups B, C, D
(OP)
We currently have a issue with a motor driving a fan heater. these heaters are used for temporary hoardings, building etc. the problem is the motor on the fan is not rated for the area, Class I Div II Group B, C, D.
We are finding it very difficault to find a motor to replace this one with the proper temp rating.
My question is,
Are there single phase, 1/2 hp, 56C frame, 1800rpm motors out there?
Is there anything that can be done to cerify a non Class I Div II motor for a Class I Div II area? Temp rating would need to be T3C (280C)

Maybe you missed the OP's "Div 2." Dive 2 means you have a lot of freedom with things that don't arc, spark, or get really hot in normal service -- see the NEC article that rbalex cited.
There are also lots of explosionproof and intrinsically safe things that are good for Group B Div 1. Group A is the tough one to find equipment for -- generally it's intrinsically safe only.
