According to regulations, motors are exempt from being what?

The regulation states that motors do not need to be individually listed or field evaluated to be compliant. This exemption exists because motors often meet standardized safety requirements and performance standards established by organizations such as Underwriters Laboratories (UL) or the Institute of Electrical and Electronics Engineers (IEEE). Therefore, as long as they comply with the appropriate standards and regulations, they can be installed without the need for unique labeling or separate evaluations for each individual unit.

The other options involve specific requirements that motors typically must meet. For instance, labeling for indoor use indicates the environment for which the motor is suitable, while the requirement for thermal overload protection is crucial to prevent overheating and potential fire hazards. The origin of manufacture, whether USA or otherwise, can also be relevant for compliance under certain regulatory standards, but it is primarily safety and performance standards that govern motor usage.
