  • Patent number: 5547404
    Abstract: A fixed spacer hot line tap has a body with a base and a run-conductor groove. An eyebolt passes through the base and has a tip disposed between the base and the run-conductor groove. The eyebolt has a tip, on which is attached an extender having at least one spline on an outer surface thereof and a tip. The extender is directed through a hole in a spacer, and is press-fit therein because of the at least one spline. The spacer has an open volume defined by the foot, a first leg and a second leg, and a main transfer component, across which electric current passes from a run conductor to a tap conductor. A pad is disposed within the open volume by attachment to the tip of the extender, which reaches there through the hole in the foot. In use, a tap conductor is disposed between the pad and the main transfer component, and is secured there by a tightening of the eyebolt. The tap conductor remains clamped there when the eyebolt is withdrawn because of the press-fit of the extender in the hole in the foot.
