Grounding Cables are made with extra flexible strand of soft drawn #30 AWG (.01”) copper and are available in three different jackets. The yellow thermoplastic elastomer jacketed cable is the standard for grounding service. It provides a combination of economy, flexibility, and durability. The service temperature ranges from 212°F to -58°F (100°C to -50°C) per ASTM F 855, Type I requirements.Features & Benefits:● The black thermoplastic elastomer jacketed cable has a smaller diameter and thinner jacket material giving it better flexibility than the yellow cable. The service temperature ranges from 212°F to -58°F (100°C to -50°C) per ASTM F 855, Type I requirements.● The PVC transparent flexible thermoplastic jacketed cable allows easy inspection for strand breakage. The flexibility decreases with low temperatures. The service temperature ranges from 194°F to 40°F (90°C to -40°C) per ASTM F 855, Type III requirements.
