For example: Fault current on a panel fed from source A could flow over several parallel ground paths until it finds the neutral to ground bond at source B. The source A GF device may not see any problem because current is returning via the neutral as expected. good yoga business names

"WebStudies have shown that 98% of all electrical faults are ground faults (Source: Woodham, Jack, P.E. “The Basics of Grounding Systems” May 1, 2003). Where fuses can protect against phase-to-phase faults, additional protection, such as protection relays, are typically required to protect against ground faults.
