Why would you have 115 vac on your neutral bus in the panel that has a separate ground buss?

Certainly your neutral bus is not properly bonded to the ground buss and grounding electrode conductor. But the size of your voltage worries me. You need a competent electrician to check this one for you.

If you are measuring 115VAC on the neutral bus in a panel with a separate ground bus, it could indicate a few potential issues. One common reason is that there is a loose or disconnected neutral wire somewhere in the circuit. This could result in the neutral not being properly connected back to the transformer, leading to a voltage differential between the neutral and ground buses. It's important to investigate and address this issue promptly to prevent potential electrical hazards.

Why can't the ground wire be connected to neutral at the receptacle instead of in the main panel?
Connecting the ground wire to neutral at the receptacle can create a safety hazard called a bootleg ground, where fault currents may flow through unintended paths. It can also cause imbalance in the electrical system and interfere with the performance of GFCI outlets. It is important to always follow proper wiring practices to ensure safety and compliance with electrical codes.
Is the neutral bus bonded to the equipment ground in a subpanel?
Definitely not. The neutral wires must be put on the neutral buss and that is the only place that they are to be terminated in a distribution panel. In a distribution panel there is no ground buss, it is just the metal enclosure that is used. The ground wire is only used to return a system fault back to the distribution panel to trip that circuits breaker.Distribution panels typically have two "busses"-- one for ground and one for neutral. These are terminal strips where the ground and neutral wires are connected. In some panels, these busses are electrically connected or "bonded." In other panels they are isolated. Most panels come with an optional "bonding screw" that can be installed or removed depending on whether the busses need to be connected. NEC is very specific on when these busses are to be connected. Ground and neutral busses should only be bonded at the main panel where the service enters the building. Other distribution panels will have separate ground and neutral busses and they should be isolated electrically--connecting these is a commonly seen mistake.I believe the question refers to the case where the two busses are properly bonded together, so are electrically equivalent. Then is it acceptable to have some ground wires on the neutral bus and vice-versa. Electrically it will work, but code or electrical inspectors may deem it to be confusing or sloppy practice and reject the installation.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How do you connect the wires for a 200 amp sub panel to a 200 amp main panel?
You will need to install a 4-wire feeder cable between the two panels. The two hot wires will connect to the main breaker in the main panel, the neutral wire to the neutral bus bar, and the ground wire to the ground bar. Make sure to follow local electrical codes and regulations. If you are unsure, consult with a qualified electrician.
When wiring a 120V outlet from a 240V 3 wire service can you just connect the neutral white to the middle wire of the 240 and grab a ground from another source?
No, you should not connect the neutral wire of the 120V outlet to the middle wire of the 240V service. The neutral wire should be connected to the neutral bus bar of the electrical panel. Additionally, the ground wire should be connected to the grounding bus bar of the panel, and it should not be "grabbed" from another source. Proper grounding is essential for safety and to prevent electrical hazards.
What does the earth pin do on a 3 pin plug?
The earth pin on a 3 pin plug is for safety and grounding purposes. It provides a path for electrical current to safely flow to the ground in case of a fault, preventing electric shocks and protecting the user from potential hazards.

Why do you have 230vdc from neutral to ground in a three phase 460vac panel?
Neutral is grounded in a distribution panel. At best, it is only a few tens of millivolts away from ground and it certainly would not be DC - it would be AC.

How do you hook up the distribution panel box with red white black and ground wires?
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 happens if neutral wire goes in earthing hole?
That would be a ground-fault if it occurs anywhere other than inside the service panel.
Where do you hook your neutral in your breaker panel if there is no neutral bar?
Unless the panel is the Main Panel (first panel in the system after the service feed) all panels have a neutral bar. Otherwise you are missing pieces. If this is the Main Panel, the neutral bar is bonded to the ground by a bus-bar. If this is the case, neutrals should all be connected to the same side of these bonded bars. Electrically it makes no difference, however it is a good practice to keep electrical panels neat and organized. If this is not the Main Panel and there is no neutral bar, STOP, PUT DOWN THE TOOLS, CALL A PROFESSIONAL. This panel is missing pieces and may be dangerous. It is possible to have a panel without a neutral. This panel would serve only 240 volt loads where no neutral is needed, however I have not seen this done in residential applications.
Will a GFI outlet keep tripping because it's line is wired to a fuse box panel where the neutral and ground are together?
No, that alone would not cause a GFCI to trip because that is the proper way to wire a panel.
What would happen if a wire is cut between the wall switch and ceiling light?
The light wouldn't go on unless just the neutral was cut and there was a separate ground.
