What needs to be done to troubleshoot a ground fault on switchboards?

The best approach to troubleshoot a ground fault on switchboards is to inspect physical wiring. Ground faults can be caused by damaged insulation, loose connections, or other physical defects in the wiring that can lead to unintentional current paths to ground. By inspecting the physical condition of the wiring, you may identify issues such as frayed or broken wires, corrosion, or other physical damage that could be causing the ground fault.

When grounding issues are suspected, checking the wiring directly allows for identification of the specific source of the fault and ensures that any necessary repairs or replacements can be made effectively. This step is essential to safely resolving the issue and restoring normal operation to the switchboards.
