Single Assemblies • Grounding Cable Clusters • URD Grounds
The clamps in any assembly can be identical or quite different depending on each grounding application. JM Test Systems stocks a wide variety of clamps for ALL applications. Clamps are offered in either bronze or aluminum alloys and are manufactured to meet the current specifications of ASTM F 855.
To attach a clamp to the grounding cable requires the use of a ferrule. Ferrules are compressed on the strands of the cable to provide a low resistance permanent connection. The size of the ferrule is determined by the size of the cable. Ferrules are manufactured to the specifications of ASTM F 855.
Grounding Cable Checklist
1. Specify the clamps. Be sure that the clamp will meet or exceed the max amperage rating of the ground cable that it will be used with.
2. Specify the cable. Once the short circuit capacity of the system has been determined, choose the appropriate size cable. Specify the cable length, and the color of the jacket desired.
3. Specify the ferrules. The size of the ferrules must match the size of the cable that it will be used with. Specify Copper or aluminum and shrouded or non-shrouded.
4. Specify the options. List any optional equipment that is desired. This can include hanger studs, contact studs, heat shrink tubing, markings, clear strain relief, etc.

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 200º to -50ºF per ASTM F 855, Type I requirements.
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 200º to -50ºF 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 140º to -40ºF per ASTM F 855, Type III requirements.
The silicone transparent flexible thermoplastic jacketed cable allows easy inspection for strand breakage. The service temperature ranges from 302º to -40ºF per ASTM F 855, Type I requirements.
