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.

Can neutral and ground wires be connected to the same buss bar in a service panel?
No, neutral and ground wires should be kept separate in a service panel to prevent any potential safety hazards and ensure proper grounding. The neutral wires connect to the neutral bus bar, while the ground wires connect to the ground bus bar. Mixing them on the same bus bar can create potential electrical hazards.
Can grounds and neutral wire share same buss 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.
Does the white and ground wire connect to same ground bar in a meter base?
There should be no ground wire in the meter stack from the mast head to the meter base. If the meter base to distribution panel conduit is PVC, then a green grounding conductor must be pulled into the conduit. This green wire is independent and isolated from the neutral wire and should never be terminated together at this point. Only the line service conductors and the neutral wire go through the meter base. The neutral goes through a lay in lug. This type of lug requires the insulation to be stripped of of the wire where it passes over the lug. This stripped wire is then laid into the lug and is secured to the meter base by the removable top piece of the lug. The neutral wire remains unbroken from the mast head to the distribution panel's neutral buss bar. Using this lay in lug the watt meter picks up the neutral wire for the plug in meters operation. If your terminology is not correct and you mean the "distribution panel" instead of "meter base" then the answer is no. There are two individual buss bars in the distribution panel. In some panels there may not be an actual "ground buss bar" but ground screws lined up in a row in the back of the distribution panel's enclosure. In all distribution panels there is a neutral buss bar where all of the neutral conductors from the branch circuits connect. Do not mix the bare ground wires and the white neutral circuit wires under this neutral buss bar.
Can you connect a ground to a neutral bar?
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.
Why would both ground wires and neutral wires be on same buss bar?
Ground wires and neutral wires are connected to the same bus bar in a main electrical panel to provide a safe path for current in the event of a fault. The neutral wire carries the current back to the source, while the ground wire is designed to carry any fault currents safely to the ground. Keeping them separate helps to ensure proper functioning of the electrical system and reduce the risk of electrical hazards.
Why would you have 115 vac on my 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.
Can grounds and neutral wire share same buss 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.

Why would you have 115 vac on your neutral bus in the panel that has a separate ground buss?
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.
Can ground and neutral wires go to same busbar in panel?
In the main panel, the ground and neutral wires should be connected to separate busbars for safety. This helps prevent the mixing of neutral and ground current, reducing the risk of electric shock and fire hazards. In subpanels, the ground and neutral wires must be kept separate as well.
Can the bare grounded neutral conductor of a service be buried directly in the ground?
No, the bare grounded neutral conductor of a service should not be buried directly in the ground. It should be installed above ground or within a suitable raceway or conduit to provide proper protection against damage or corrosion.
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.
What is the difference between the neutral and ground bar?
The neutral bar carries current during normal operation, conducting return current back to the source. The ground bar connects grounding conductors to the electrical panel, providing a path to safely dissipate fault currents. While both bars are connected to earth ground, the neutral bar carries normal operating current, while the ground bar is for safety in case of a fault.
Do the grounding conductors and bonding conductors ever connect to a common point?
Answer for USA, Canada and countries running a 60 Hertz supply service.The grounding electrode conductor is brought into the main disconnect section of the distribution panel and a connection is made to the neutral block. The terminations in the panel at this point are two incoming "hots" to the main breaker and a neutral wire to the neutral terminal block. In the neutral termination block there is a ground screw that screws through to the distribution panels metal enclosure, there by making the metal enclosure the same potential as the ground plate or rods and the neutral wire that comes in from the street. The grounded circuit conductors of the wiring system are terminated on a separate ground buss that is located in the circuit breaker section of the panel. This buss is bolted directly to the rear of the distribution panel's metal enclosure in the circuit breaker section of the distribution panel. This ground buss is at the same potential as the ground electrode conductor above because of the grounding screw that connects the neutral block to the metal enclosure. Code requires when wiring sub panels within the same building that the neutral block screw be taken out of the circuit and a separate ground wire be run directly from the main distribution panel. This is to prevent any short circuit currents from the sub panel traveling back on the sub panel feeder's neutral wire.In house wiring you have earth ground connect to the ground bus in the main electric panel. Your neutral bus is "bonded" to the Ground bus only at the main panel. When you run branch panels you do not connect neutral to ground in these branch panels, only the main panel. There is typically a screw in an electric panel where the bonding occurs.
