Abstract: An electrical distribution apparatus configured to connect a load to a power source is disclosed. The apparatus includes a housing having an air inlet and an air outlet, a distribution conduction path, a thermal sensor in thermal communication with the conduction path, an electrical disconnect, and an airflow generator. The electrical disconnect is connected in series with the conduction path and is configured to isolate the load from the power source on command, the disconnect being in signal communication with the thermal sensor. The airflow generator is in signal communication with the thermal sensor and is arranged to cause air to flow into the air inlet and out of the air outlet. The airflow generator is configured to turn on in response to the thermal sensor sensing a first temperature, and the disconnect is configured to disconnect the load from the power source in response to the thermal sensor sensing a second temperature greater than the first temperature.

Abstract: A circuit breaker support assembly allows a pair of industrial-rated molded case circuit breakers to be double-branch connected within a lighting panelboard enclosure. One of the branch circuit breakers can then operate as a main circuit breaker thereby eliminating the separate main circuit breaker commonly used within such lighting panelboard enclosures.
