When you install 1000V PV systems, obviously the current-carrying wires have to have insulation rated at 1000V or greater.
What about the equipment grounding conductor? Is there any rule requiring an insulated EGC to have the 1000V rating? Given that an EGC can be bare wire, for which voltage rating isn't applicable, can an EGC still have a 600V rating in a 1000V system?
