Grounding means → A permanent and continuous conductive path to the earth with sufficient ampacity to carry any fault currents liable to be imposed on it, and to facilitate the operation of the protective devices in the circuit,
Bonding means → a low impedance path obtained by permanently joining all non-current-carrying metal parts to assure electrical continuity and having the capacity to conduct safely any current likely to be imposed on it
