Abstract
An electrically and thermally protected electrical machine is disclosed. The electrical and thermal protection is provided by one or more control components placed in a conduit box of the electrical machine to disrupt power transmission to the electrical machine upon an excessive current or temperature occurrence. Other control components may also be added to the system to provide further current or thermal protection. These additional control components may or may not be located within the conduit box. A method for providing thermal and current protection, and an aftermarket kit for adding such protection, to an electrical machine are also disclosed.
