Multiple Choice

Within what distance of power must above-ground apparatus be bonded to power neutral?

Bonding exposed metal to the power neutral within a short distance from where power enters keeps all these parts at the same electrical potential. This creates a low-impedance path for fault current, so if a fault energizes the equipment, the current returns quickly to the source and the protective device trips, reducing shock risk. If bonding were done farther away, impedance rises and a potential difference could exist between metal parts and the neutral, increasing the chance of shock. Therefore, the required distance is six feet.
