ABSTRACT:
A ground rod, coupling therefor and method of making that coupling are disclosed providing both strength and improved conductivity. Ground rods are usually copper coated or plated steel rods formed in sections which are driven or, perhaps more correctly, pounded into the ground to form grounding or earthing connections for dissipation of electrical current into the earth. The coupling includes co-extensive inner and outer sleeves of copper and a corrosion resistant metal such as stainless steel, respectively, which are mechanically interlocked along their axial lengths. The inner copper sleeve is formed with threads or oppositely directed cones after the two sleeves are interlocked and in so doing the interlock between the sleeves is enhanced. If the connection of the coupling to the rod is threaded or a simple cone friction fit, the connection and/or driving of the rod sections yet further works the internal copper sleeve enhancing both copper-to-copper electrical conductivity and the interlock of the inner and outer sleeves.
