摘要：A lighting track system according to the invention provides an elongated
metallic track generally in the shape of an inverted U, with an elongated insulator美丽心境
extending through the track and including polarized pairs of neutral and power electrical conductors in one or more slots. A flexible cord and polarized plug electrically and
mechanically connects to a pair of conductors in the track and prevents connection of the polarized plug with reverd polarity of the power and neutral conductors. In a preferred embodiment a polarized plug and cord is an end-feed that connects a track circuit to an electrical main circuit, or may connect a track circuit to a track-supported light fixture. In the preferred embodiment a polarized plug on each end of the flexible cord connects adjacent lengths of track. In the preferred embodiment a rrated ground engages a dovetail slot in the metallic track to ground track lengths and fixtures.
