Abstract: A ballast assembly for a lamp includes a housing that receives a circuit board assembly therein. The circuit board assembly preferably has first and second board portions disposed in physically spaced, parallel relation. The board portions are interconnected by a conductive member, preferably a flexible conductive member. The spacing between the board portions is preferably substantially identical to a maximum height dimension of a tallest electrical component extending outwardly from one of the first and second board portions. A separate mounting bracket mechanically secures the housing to an associated surface and constrains the housing along at least one of first, second, and third perpendicular axes. Preferably, the mounting bracket is a one-piece construction where first and second ends of the bracket are laterally off-set, and the bracket can also serve as a heat sink to the ballast housing.

Abstract: An electrical sub-metering system for making available information associated with power consumption is disclosed. The system includes an electrical panel board configured to distribute power to a plurality of circuits, means for measuring voltage of each circuit, a module including means for measuring current flow, a hub in signal communication with the module and the means for measuring voltage, and a data collector in signal communication with the hub. The hub is configured to collect the information associated with power consumption from the means for measuring voltage and the module, and the data collector is configured to collect and make available to a user the information associated with power consumption for each circuit. The module is in signal communication with the hub via a single communication link, the single communication link having a plurality of communication paths.
