In any distribution panel there are individual bars for each termination. The ground buss is in direct contact with the metal enclosure. The neutral is isolated from the metal enclosure. The only place where the two come into contact with each other is where a bonding screw protrudes through the neutral bar and into the metal enclosure.
No, the ground and neutral wires should not share the same bus bar in an electrical panel. The ground wire is for safety and should be connected to the ground bus bar, while the neutral wire is for returning current and should be connected to the neutral bus bar. Mixing them can cause dangerous conditions like electrical shock or fires.
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.
Take a look at the junction where the ground wire and the neutral enter the panel. There you should see a green grounding screw that protruded through the neutral block and into the metal enclosure of the distribution panel.
No. The sub panel is wired that same as an ordinary three wire load. The three wire is connected the sub panels terminal points as red to L1, black to L2, white to the neutral bar and the ground wire in the cable set to the ground bar. The one thing that has to be done is the bonding screw that bonds the neutral bus to the panels metallic enclosure has to be removed. The electrical code states that there is only one place that the ground is joined to the neutral bar and that is at the service entrance point into the main distribution panel.

A neutral bar is where the neutral wires from the circuits are connected, while a ground bar is where the ground wires are connected. The neutral bar carries the current back to the power source, while the ground bar provides a path for excess electricity to safely dissipate into the ground.
A ground bar is used to connect the grounding wires of electrical circuits to the panel's grounding system, while a neutral bar is used to connect the neutral wires of electrical circuits to the panel. The ground bar is for safety, while the neutral bar is for completing the circuit.
It shouldn't. The open end of a non connected neutral should have the same potential as the voltage feeding the circuit. The only time a voltage will show is when the return neutral is tested with a meter to the neutral bar or the ground return bar. It will then show what the supply voltage to the connected load is. Once this neutral is connected to the neutral bar there will be no voltage shown across the test meter between the neutral and the neutral bar or the ground bar.
No, the ground and neutral wires should not share the same bus bar in an electrical panel. The ground wire is for safety and should be connected to the ground bus bar, while the neutral wire is for returning current and should be connected to the neutral bus bar. Mixing them can cause dangerous conditions like electrical shock or fires.
Without more information that appears to be a 240 volt circuit. Red & black would connect to the 240 volt breaker, white connects to the neutral bar, and ground conductor from the ground rods or ground plate connects to the neutral bar. Make sure that the bonding screw is in the neutral bar and it is screwed through to bond the distribution panel enclosure to the neutral bar.

What is the difference between a pub and a resto bar?
Take a look at the junction where the ground wire and the neutral enter the panel. There you should see a green grounding screw that protruded through the neutral block and into the metal enclosure of the distribution panel.
I think there is no difference between them. They just do it to get your money.
Ground fault breakers monitor the current on the neutral wire flowing back to the neutral bar, a 4 to 6mA difference will trip the breaker, Shunt trip breakers on the other hand can be tripped remotely from some other type of switch or location. In industrial applications it is used to shut power off in an emergency situation, when access to an electrical panel may denied.
No, the ground and neutral wires should not be connected to the same bar in an electrical panel as they serve different purposes in the electrical system. Connecting them to the same bar can create safety hazards and cause electrical issues.
