Of Electrical Distribution Systems with Multiple Grounded Neutrals

Multiple grounded neutral systems require that, on most land-based AC current service installations, the bonding conductor used to connect the non-current-carrying metal parts of equipment, the system grounded conductor (neutral), and the grounding electrodes be bonded together at the service entrance box. Users, thus, share their ground with the serving utility´s neutral ground. This interconnection, although functional, poses some distinctive problems to utility companies as well as to users, which this paper seeks to clarify
