No, you cannot bond the neutral to the ground on the new device and then to the metal device box and call it a day. This is because the neutral and ground conductors serve different purposes and must be kept separate. The neutral conductor carries the current back to the power source, while the ground conductor provides a path for fault currents to flow to the ground. Bonding the neutral and ground conductors together would create a short circuit and could result in a fire or shock hazard.The correct way to add a ground wire to an existing two-prong outlet is to install a three-wire branch circuit. This involves running a new cable from the electrical panel to the outlet, which will include a ground wire. The ground wire must be connected to the ground terminal on the outlet and to the metal device box. Flag for review
