Abstract: A ground contactor couples to the space between the pipe fitting used in the electrical supply conduit. The contactor consists of a knife-edge contacting surface having a screw thread adjustment located at the surface. The screw thread is a pointed screw thread which is adjustable without removing the contact surface for the space. The contact surface is clamped by a U-shaped clamp and tightened securely in the pipe fitting space. Angular contact surfaces are provided at the points of threaded adjustment between the clamp and the contactor so that forces are created for adjusting the clamp relative to the contact surfaces to permit the device to be used on conduits of different diameters. The contactor thus shaped and configured permits permanent electrical ground contact to be achieved and also permits serviceability of the electrical conductivity of the conduit connection arrangement without the necessity to move or otherwise disturb the ground contactor installation.
