Do you mean besides the protection offered by the OCPD in the event of a direct short to ground? Does anyone even make a GFP device for circuits carrying that much power?Are the pump inside pump station (water treatment plant) required ground fault protection?
If the pump is located under water, I assume it needs GFP protection?
