Abstract: A cable tap system is disclosed for selectively connecting a plurality of tap terminals to a plurality of conductors in either a continuous multi-conductor electrical cable or in two ends of two such cables butt up to one another. A closable cable clamp assembly clamps onto the continuous cable or cable ends. A terminal holder is positionable against one side of the cable clamp assembly and mounts a plurality of tap terminals for interconnection to the conductors of the cable. A backing member is positionable against an opposite side of the cable clamp assembly. A plurality of rotatable fasteners are operatively associated between the terminal holder and the backing member for sandwiching the cable clamp assembly therebetween and maintaining the tap terminals interconnected with the conductors of the cable. A tool is provided for simultaneously rotating the fasteners to close the terminal holder and the backing member in a uniform action.
