  • Grounding of the neutral circuit in the distribution box

    Grounding of the neutral circuit in the distribution box

    Bonding (connecting) the neutral and ground should only occur in the main panel or at the first service disconnect. In a service equipment (main panel) and remote distribution panel (subpanel), the ground terminal must be connected to a ground rod using an equipment. Grounding is a mechanism to protect distribution equipment and people under normal operating conditions, abnormal operational (overcurrent and overvoltage) responses, and hazardous conditions such as shocks. Grounding is necessary to assure correct operation of electrical devices, to assure safety. A neutral bar connects neutral conductors and normally carries return current back to the supply source. In main service equipment. Safety of Personnel: By safely channeling fault currents into the ground, proper grounding helps to reduce the risk of electric shock to personnel. They should never be connected together downstream of the service equipment, such as in subpanels or other parts of the circuits.
