Where can underground cable circuits originating in pad-mounted switchgear be grounded?

Grounding underground cable circuits originating in pad-mounted switchgear is best accomplished near the cable termination. This method enhances safety and system performance by ensuring that the grounding system is in close proximity to the cable, which minimizes the potential for electrical faults and disturbances in the system.

Grounding at the termination point allows for an effective path for fault currents to safely dissipate into the ground. This is critical for protecting equipment within the system and for ensuring the safety of personnel who may be working in the vicinity.

Grounding at other locations, such as at the utility pole, meter location, or main service panel, does not provide the same level of effectiveness in managing electrical faults that can arise at the cable itself. These other points may introduce additional resistance in the grounding path and may not adequately mitigate the risk of equipment damage or electrical hazards. Therefore, grounding near the cable termination remains the most appropriate choice for safety and reliability.
