Neutral and ground wires are usually bonded together at the main service panel of a building, but should never be bonded together at any subpanel or other point downstream. This connection is made to provide a safe path for stray electrical current in case of a fault, and to ensure proper grounding and equipment safety.
No, in a sub-panel of an outbuilding, the neutral and ground should be kept separate and not bonded together. This is to prevent the potential for ground loops and to ensure proper functioning of the grounding system.
Some electric panels have the ground and neutral bonded together for safety reasons. This bonding can help prevent dangerous voltage levels and reduce the risk of electrical shocks in case of a fault. However, it is important to check local electrical codes and guidelines before making any modifications to ensure compliance and safety.
Neutral and ground wires are sometimes bonded to ensure electrical safety by providing a path for fault current to flow back to the source in case of a fault. This can help prevent dangerous voltages from building up in the system. Bonding the neutral and ground wires is a common practice in dry type transformers to maintain proper grounding and ensure safe operation.
The main electric panel is where neutral is bonded to ground. There is usually a screw or strap that connects the two so the same type panel could be used as a subpanel and have the neutral and ground unbonded in subpanel.
To check if the ground wire is properly bonded to the neutral and the cabinet at the service box, you can use a multimeter to test for continuity between the ground wire, the neutral wire, and the metal cabinet of the service box. If there is continuity between all three, then the bonding is appropriate. It is important to ensure that this bonding is done correctly to provide a safe electrical system.

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

Grounding is an important part of all electrical wiring like your home. Without proper grounding you are asking for all sorts of strange problems and safety issues. The power company provides electricity to your main panel and a good ground is required. This is usually a metal rod in the ground near your meter. This ground is bonded to the main electric panel. The neutral wire is in turn bonded to ground at the main panel. If you have a bad ground, neutral can float above ground causing shock hazards. I once had to chase down a shock problem in a shower. It turned out to be a case where the neutral and ground were not bonded at the main panel. What you shouldn't do is the hot side of power to ground.

The rounded third prong goes to earth ground at the main panel where the neutral is also bonded to ground.

It is very rare to have three-phase electricity coming into a residence. One of the wires is probably the neutral (It will be white or black with white stripes.) The ground comes in from a ground rod near the main, and connects to the ground coming from the meter, AND (If the main fuse box is the first disconnecting means,) the neutral and ground bars have to be bonded together in the box.
In an AC circuit, the ground is a non-current carrying conductor that is bonded to the neutral (and earth) at the panel or service, and is also connected to the cases of all items of electrical equipment other than those which are double-insulated. In a DC circuit, ground is usually the negative battery terminal that is bonded to the frame of the DC apparatus. In a car, the negative (usually) is bonded to the frame and body of the car.
Only the main panel is grounded directly because if you ground each junction box of subpanel ground loop current paths are possible that can cause shock hazards. The ground rod is connected to main panel and the neutral is bonded to that ground as is the ground wire. The neutral and ground wire are then run to all circuits, junction boxes and subpanels throughout the house. If you tie neutral and ground together at any point in the house, other than the main panel ground loops can exist and cause shocks.
