Abstract
An electrical assembly includes a heat conducting housing. A conductor is supported by the housing and conducts electrical current. An electrical insulator member surrounds the conductor. A core surrounds the insulator member and the conductor so that current flowing through the conductor induces a magnetic field in the core. A transducer is coupled to the core for generating a signal representing current in the conductor. A thermal interface member engages the core and engages the housing. The interface member conducts or can conduct heat to the housing.
