ELECTRONIC BALLAST ASSEMBLY

摘要

An electronic ballast mounting arrangement for HID luminaires on a vertical pole for sports lighting is disclosed. The mounting arrangement comprises an elongate channel to which a weather tight enclosure is fixedly secured. Electronic ballast units are provided in pairs immediately above and/or below the enclosure. Male/female connectors are arranged between end plates of the electronic ballast units and exterior panels of the enclosure so that electrical connections between the ballast units and components on the interior of the enclosure can be made without exposed cables simply by sliding partially pre-mounted ballast units a limited distance toward the adjacent enclosure panel to mate the complemental parts of the connectors, after which the fasteners holding the ballast units to the support are tightened down. A cable using wires with a high-strand count extends through a nipple screwed into a hollow pole from the interior of the weather proof enclosure into the center of the pole and runs upwardly through the pole to the luminaires mounted on one or more cross arms on the top of the pole. A Kelem grip hanger is used to support the cable and relieve tension on the electrical connections between the cable and the luminaires.
