Ground wire can be appropriately bonded to the neutral and cabinet at the service box by connecting the neutral and ground wires from the feeder wires to the neutral bus bar and the ground terminal located on the same cabinet at the service box. White wire (neutral) must be connected to bus bar and bare wire must be connected to ground terminal in the same cabinet.
The neutral and ground are only bonded in a sub-panel of an out building if the code requires a buried ground rod or plate at this location.
The term SN refers to a panel or disconnect switch that has solid neutral bar installed. It is a small bar that allows the service conductors to be bonded to the enclosure at that point.
By National Electric Code only the Main Panel should bond ground and neutral. If subpanels have ground and neutral bonded, it could cause ground loops and shock hazards.
Neutral is neither Hot nor ground. Neutral is the return wire for electrical service. It is a requirement , by law, that the Neutral Wire Feed into an electrical service box (main panel) be BONDED to the box and the Earth ground. Thie effectively makes the neutral in circuits out of the service panel equal to ground. But as it enters the service panel from the utility and meter pan, it is not ground. <<>> The only time that the neutral can have voltage on it is if it gets disconnected from the distribution point. Then the voltage that is supplied to the load will continue through the load and stop at the disconnection point. If you touch the uninsulated part of the neutral wire and touch any grounded equipment at the same time your body will act as a conductor for the load circuit. You will receive a nasty shock. This scenario is the only time that the neutral is "hot".

Answer for USA, Canada and countries running a 60 Hertz supply service.Nothing but the neutral bus should be bonded to the ground electrode.
