Miscellaneous Products Bare Soft Copper Grounding Conductor Product Construction: Complete Conductor: Bare soft copper grounding conductors are solid or concentric-lay-stranded, consisting of one or more layers of wire wrapped helically around a straight round central wire. Each successive layer has six wires more than the layer immediately beneath. Greater flexibility is afforded by using Class B stranding. The direction of lay for the outer layer is left-hand lay. In multilayer constructions, the direction of lay for each successive layer is reversed. Copper ground wires are manufactured using annealed soft copper wire and are manufactured in accordance with the requirements of the latest applicable issues of the ASTM specifications B3 and B8. Features and Benefits: Solid or stranded bare soft copper grounding conductors are suitable for direct burial and are inherently corrosion-resistant and easy to terminate and join at splices and joints. Applications: Solid and stranded bare soft copper grounding conductors are suitable for use as neutrals, as circuit grounding conductors as well as machinery and equipment grounding systems. Soft copper may be used for transformer drop leads or other non-tension hook-up jumpers.
