Grounding and Bonding
Part I. General
Additional text helps the Code user understand that the purpose of the effective ground fault current path is to help clear a ground-fault by facilitating the operation of the overcurrent device.
Effective Ground-Fault Current Path. An intentionally constructed, permanent, low-impedance conductive path designed to carry fault current from the point of a ground fault on a wiring system to the grounded neutral point at the electrical supply source. Figure 250-1
The effective ground-fault current path is intended to facilitate the operation of the circuit overcurrent protective device, or the ground-fault detector on a high-impedance grounded system. Figure 250-2
