A connector assembly for installing a device to a ceiling grid, the ceiling grid having conductors provided therein. The connector assembly includes a housing with contact arms mounted in the housing. Contact portions of the contact arms extend from the housing and are placed in electrical engagement with the conductors when the connector assembly is mated with the ceiling grid. Mounting members extend from the housing. Mounting sections of the mounting members are placed in mechanical engagement with the ceiling grid to provide a mechanical connection between the ceiling grid and the connector assembly. A polarity protection/correction member is provided in the housing. The polarity protection/correction member protects the device from failure or damage when the polarity orientation of the device does not match the polarity orientation of the conductors of the grid.
