Product Description
Bare Copper Conductor Stranded
Hard, Medium-Hard, or Soft-Drawn
Used for grounding purposes in accordance with the National Electrical Code (NEC). Soft-drawn solid or stranded conductors are used for grounding connections in circuits, machinery, equipment, and counterpoise grounding systems. Hard-drawn conductors are suitable for overhead transmission and distribution lines and specified grounding applications. Also available tinned.
