502.125 (B) Class II, Division 2 Motors lists 5 different types of motors (totally enclosed nonventilated,totally enclosed pipe ventilated, totally enclosed water-air-cooled, totally enclosed fan cooled, and dust ignitionproof). The final motor type listed in the list is dust ignition proof which is followed by a referrence to 500,8(C)(2). Is this reference valid for all 5 motor types are only for the dust ignition proof?
Main question is really: Is the electrician required to hook up thermals on motors in a Class II Div 2 area? Argument is that a TEFC motor does not need to have thermals hooked up since it alreay is equipped with a fan to provide cooling and keep the external temp safe.
