What is required for equipment grounding conductors installed in raceways for isolated ground receptacles?

For equipment grounding conductors installed in raceways for isolated ground receptacles, the requirement for them to be insulated is crucial. Insulation on grounding conductors helps to prevent accidental contact with live conductors, which could lead to short circuits or electrical shock. In the context of isolated ground receptacles, the insulation serves the additional purpose of minimizing the risk of induced voltages from surrounding conductors, ensuring the effectiveness of the isolated grounding system.

While other attributes such as being made of copper or having specific insulation colors may have their own relevance in different contexts, the primary focus here is on the insulation of the grounding conductors specifically to enhance safety and performance in the grounding system. Similarly, while the idea of being continuous is important for the integrity of grounding pathways, it is the insulation that directly addresses the issues associated with isolation and safety in electrical installations.
