Abstract: For use with standard junction boxes, mounting structures for supporting electrical fixtures in the junction boxes, the mountings including in each modification illustrated in the drawings a fixture holder bracket which has a bottom portion supported on two leg portions which lie parallel to the side walls of a standard junction box, the leg portions having at their upper ends attaching means for attaching the bracket to the junction box, and the bracket having in their bottom portion specially shaped edges which are formed upwardly in such a way that the edges first diverge, and then converge so as to provide a clip structure adapted to receive and tightly grip the inner mounting portion of an electrical fixture which is snapped into the bracket, the bracket being supported on the junction box, and the fixture being in turn supported by the bracket within the junction box.

Abstract: A terminal block for mounting in a junction box and for terminating electrical power feed conductors and joining them to other power distribution wires, the block which has particular utility in multiple phase power systems has a different lug for each phase, each lug having multiple cable receiving bores with set screws for securing the cables in the bores, the set screws all being accessible from the exposed outer surfaces of the block, and the lugs being supported side by side in an insulating housing mutually separated by partitions, the housing having a cover for covering all the lugs.
