Common or separated grounding, DC cable is routed above ground or underground in a cable trench in the LPZ 0 area. T1 DC SPDs are required; T1/2 is recommended.
Temporary (Portable) Protective Grounding Requirements
(4) Grounding cables should be no longer than is necessary to keep resistance as low as possible and to minimize slack in cables to prevent their violent movement under fault conditions. If the circuit should be inadvertently reenergized, the fault current and resultant magnetic forces could cause severe and dangerous movement of slack grounding …
