By the grounding of the secondary common, the rated voltage of the single-phase AC windings in the secondary of the supply transformer sets the maximum operating voltage of the ungrounded transmission/distribution lines in reference to earth ground such that the energy of the. Safety of Personnel: By safely channeling fault currents into the ground, proper grounding helps to reduce the risk of electric shock to personnel. This helps to reduce the potential difference that exists between conductive parts and the earth. According to NEC Article 250, neutral and ground wires must remain separate in subpanels.
