Copper Grounding Cable is extra-flexible for handling ease yet strong and tough for long wear. Jacketing is smooth, abrasion, weather and oilresistant in accordance with applicable ASTM Specifications, marked with AWG size approximately every 4 feet. Clear jackets (which allow visual inspection of strand conditions) are ultraviolet inhibited Poly Vinyl Chloride (PVC). Recommended low temperature for PVC-jacketed cable is 0?F. Extra-flexible cables, because of their extra-fine strands, require termination ferrules when used with grounds.
