What is the typical voltage rating of jacket material used on grounding cables?

The typical voltage rating of jacket material used on grounding cables is predominantly 600 V. Grounding cables are designed for safety and effectiveness in providing a path to ground for electrical systems.

Typically, these cables do not carry voltage like other conductors; instead, their primary role is to ensure safety by directing excess electricity or fault current safely into the ground. Therefore, a 600 V rating is appropriate for most applications, providing a sufficient level of insulation to handle the expected operational conditions while maintaining safety standards.

Higher voltage ratings, such as 1,000 V or more, are usually reserved for specialized applications that require enhanced insulation and mechanical protection against electrical stresses. Grounding systems primarily operate under lower voltage ratings because their function does not involve carrying voltage during normal operation, making the standard 600 V rating both sufficient and practical for general use.
