A submersible electrical connector intended for use in a power distribution network permits a metal to stripped metal conductor connection to be visually inspected and verified by the installer while eliminating many opportunities for human error present with existing connectors. The connector in one embodiment includes a generally cup or dome-shaped enclosure which is preferably transparent. An open end of the enclosure mates with an upper seal body and a connector plate has a number of apertures adapted to receive the bare metal ends of conductors or wires inserted through the upper seal body. Each aperture in the connector has an associated set screw for securing the conductor thereto. A molded seal member is adapted to mate with the upper seal body and to provide a water-tight connection when mated with the enclosure. The seal member has a number of seal ducts each aligned with one of the apertures in the connector. The seal ducts provide a water-tight seal around the plastic sheath of the conductor when installed in the assembly. Each seal duct initially includes a missile-shaped wire way guide plug inserted therein. Each wire way guide plug can be opened at the bottom to receive the exposed end of the conductor therein. The wire way guide plugs remain installed in the seal ducts to seal them until a conductor is inserted through the associated seal duct.
