Why do some electric panel have ground and neutral bonded together?

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.

What is the difference between ground and floating neutral in your electric panel?

At the main service panel, the grounding and neutral bars are bonded (connected together). At sub-panels they are NOT bonded together, hence the term "floating neutral".

Is the neutral bus bonded to the equipment ground in a subpanel?

Neutral and ground are only bonded at the main panel, not subpanel.

Can earth be used as neutral?

Neutral and ground should be separate and bonded together only at the main panel for a business or residence.

In standard 120 volt wiring what are the colors?

Black is hot, white is neutral and bare wire is ground. Neutral and ground are bonded together at the main panel.

Are the neutral and ground bonded in a sub-panel of an out building?

The neutral and ground are only bonded in a sub-panel of an out building if the code requires a buried ground rod or plate at this location.

When is the neutral grounded in an electrical circuit?

The Neutral is bonded to the ground at the FIRST main breaker, which is usually just as it comes from the meter. In normal residential applications, power comes from the meter, then to a panel. In that panel, the ground and neutral are bonded. If that panel feeds another panel, the second panel has to have its ground and neutral separated. Mobile homes have to have a main breaker outside the house, so the neutral is grounded there, and inside the mobile home, they are separated.

Where is the only place the neutral and ground wires can be on the same buss bar?

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.

Why is neutral and ground wires sometimes needed to be bonded in a dry type transformer?

With very few exceptions your neutral and ground are always bonded together at the service. They can be bonded together anywhere from the transformer to the first overcurrent device, usually a panel, but in the transformer is where it is usually done. Bonding the neutral keeps your voltages from floating. Without going into very technical explanation, suffice it to say that without proper bonding you can get different voltages supplied to various circuits in the building or home. Higher voltages can cause burn out of fixtures or equipment and lower voltages can burn up motors or keep lights from providing adequate light.

Why can't the ground wire be connected to neutral at the receptacle instead of in the main panel?

First off, this is for a single phase 120/240V system only. The ground and neutral can be bonded at the receptacle but not instead of bonding them at the panel.You should always have them bonded together at the panel in a single phase 120/240V system. Otherwise you risk having a floating neutral in your system.

How can you tell if the ground wire is approriately bonded to the neutral and the cabinet at the service box?

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.

What is the job of neutral wire?

Completes the circuit to ground. In a home or commercial power center, neutral is connected to ground at Main Panel which is bonded to earth ground. The neutral is the return path back to the utilities transformer and is bonded to the grounding conductor at the main service equipment.

Can the neutral and ground be bonded at the meter box?

It is more usual to ground the neutral back at the transformer. This decouples the local earth wire from the supply wires.

What are the black and white wires in a plug?

Black is HOT and white is Neutral. Neutral is bonded to ground at main panel.

Why shouldn't you ground electrical wiring?

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.

Why are the GFCI breakers nuisance tripping in your 100 amp sub panel- is it because neutral bonded to ground?

It may be the GFCI breaker is defective. Make sure it is wired correctly. Neutral to neutral bar and ground to ground bar.

What does the white wire do when there is no neutral?

In standard residential wiring there is a black (hot), white (neutral) and bare wire (ground). There must be a neutral, so not sure what you mean. The neutral and ground are bonded to each other at the main electric panel.

What besides the neutral system should be bonded to the ground?

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

Can the neutral and the ground be connected to the same terminal on a service panel bus?

In North America the ground and neutral only come together on the main neutral bus. On a combination panel this bus is in the main breaker compartment of the panel. Also this is where the panel enclosure is bonded to the neutral and ground wire through a bolt that passes through the neutral bus and screws into the panels enclosure. On sub panels from the main panel this bonding bolt has to be removed.

Can neutral and ground be wired together?

No, they should not be wired together.

The what of an electrical plug connects the metal to the ground?

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

What happens when neutral is bonded to ground wire most especially to dry type transformers?


There are only 3 phases that come into house main fuse box so where does ground and neutral come from?

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.

What is meant by AC and DC grounds?

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.

What happens to the neutral wire when it returns to the breaker box?

All the neutrals are connected together on a bus bar and are bonded to the equipment grounding conductor and the grounding electrode conductor which goes to the ground rod.
