A modular junction box device that houses port sub-housings which each contain electrically-conductive connector clips that facilitate quick, push-in electrical connection of the hot, neutral and ground wires within a supply wire cable leading from a power source with the corresponding distribution wires leading to each of any number powered devices. The invention utilizes internalized push-in connectors to allow a single supply electrical wire cable (line in) to be connected to multiple distribution wire cables (lines out) without the need for a proportionate amount of internal wiring that ordinarily connects supply and distribution wires inside of a junction box.
