What is required of the impedance grounding conductor in a grounded system?

In a grounded system, the impedance grounding conductor plays a crucial role in ensuring safety and proper functionality. For this conductor, being fully insulated is vital to prevent any unintended grounding or electrical faults. Full insulation helps to protect against short circuits and ensures that the conductor operates safely within the electrical system without unintended interference or hazards.

Additionally, restricting connections on the supply side is also important. Keeping the supply side free from connections ensures that the grounding system operates effectively as designed. It prevents the introduction of additional impedance that could compromise the grounding's protective capabilities.

Thus, requiring the impedance grounding conductor to be fully insulated while also prohibiting connections on the supply side contributes significantly to the overall safety and reliability of electrical systems. Each aspect is integral to maintaining the intended performance of grounded systems.
