Any above-ground apparatus within 6 feet of power must be bonded to power neutral.

The main idea here is to keep metallic parts at the same electrical potential so a fault won’t create a dangerous shock when a person touches them. Bonding creates a reliable, low-impedance path that ties exposed metal to a reference point in the power system. Bonding to the neutral conductor ensures that any above-ground apparatus within six feet of power shares the same potential as the return path of the supply. Because the neutral is bonded to earth at the service, this effectively places those metal parts at the same potential as the earth/ground, helping fault current flow back to the source and tripping protective devices quickly. This reduces shock risk if a live conductor contacts the equipment. In practice, bonding to protective earth and bonding to neutral are functionally equivalent for establishing a safe, common potential, since neutral and earth are tied together at the service disconnect. Not bonding would leave equipment at an unknown potential, increasing shock risk. Bonding to neutral aligns with the stated requirement and achieves the same protective result.
