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.

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 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.
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.
Splicing the ground wire and neutral wire together in a high hat fixture is unsafe and can create a dangerous electrical situation. The ground wire is meant for safety and should never be connected to the neutral wire, as it can lead to electric shock hazards and disrupt the proper functioning of the electrical system. It is important to always follow proper wiring practices and consult a qualified electrician for any electrical work.
