The neutral wire carries return current from electrical devices under normal operation, completing the circuit back to the power source, while the ground wire is a safety conductor designed to carry current only during a fault to prevent electric shock or fire . When neutral and ground are connected together in a distribution box or subpanel, the ground wire can carry normal operating current, creating a parallel path for return current. This can energize metal enclosures, conduits, or other grounded components, posing a shock hazard .
Connecting neutral and ground together in a distribution box or subpanel is unsafe and code-violating. It can lead to electric shock, fire hazards, and malfunctioning of protective devices. The only acceptable location for bonding neutral and ground is the main service panel, while all downstream panels must maintain strict separation to ensure safety and proper operation of the electrical system .
