<p>A suspended ceiling grid tee of conventional cross- sectional shape having a plurality of generally planar parallel and orthogonal surfaces and at least two electrically isolated conductor strips attached to the planar areas of the tee surfaces extending along substantially the full length of the tee, a connector for supplying low voltage electrical power to or from the conductors, the connector having a configuration complementary to the cross-sectional shape of the grid tee and including at least two electrical contacts for energizing each of said conductor strips when said connector is positioned on said grid tee.</p> |
