ABSTRACT:
A mounting arrangement for mounting a ballast transformer to a structural support member. As employed in accordance with the invention, the ballast transformer has an opening through the core portion thereof. A pair of L-shaped mounting members are mounted to the ballast transformer by means of a pair of elongated, compressible mounting pins, commonly known as "rollpins," which are driven through openings in the vertical portions of the L-shaped mounting members into opposite entrances of the opening in the ballast transformer. The mounting members are then secured to the structural support member by means of threaded fasteners which are inserted through openings in the structural support member and threaded into openings in the horizontal portions of the L-shaped mounting members. The threaded fasteners are selected to have lengths so that the threaded portions thereof will extend past the exposed ends of the mounting pins and be immediately adjacent thereto. As a result, the pins are locked positively in place and are prevented from being removed accidentally from the opening in the core portion of the ballast transformer and the openings in the vertical portions of the L-shaped mounting members.
