Electrical components can be challenging to understand.
While most people are aware that touching a neutral wire is incredibly dangerous, it’s often assumed the same goes for a neutral bus bar.
Perhaps, it has to do with the name having “neutral” in it?
This leads one to ask, can you touch the neutral bus bar?
You can touch a neutral bus bar. The reason has to do with the amount of electrical current going to the neutral bus bar as it transitions through the circuit. The load will already have consumed the voltage and what’s leftover goes to the neutral bus bar. This is why you can easily touch the neutral bus bar without getting shocked.
Of course, this does not mean it’s recommended to start touching different live electrical components including the neutral bus bar.
If you do work with electrical components within a circuit, please turn off the main electrical source. This is mandatory and does not change for a neutral bus bar.
Here is more on the neutral bus bar and how it works.

What Happens If You Touch Neutral Bus Bar?
Nothing happens if you touch a neutral bus bar. This acts as a conductor within the electrical circuit and does not carry voltage in a manner that would be harmful. Any current that passes through will already have been used by the load before it travels to a neutral bus bar.
In many cases, you can place the neutral bus bar right up against your body and nothing will happen.
Of course, this is not appropriate and is still an unsafe practice. You are highly recommended to avoid handling a neutral bus bar recklessly.
If the circuit has not been grounded properly, this can still be quite dangerous for the person handling a neutral bus bar. Remember, the assumption is everything is properly in place for you to touch a neutral bus bar.
Can A Neutral Bar Shock You?
Assuming the circuit has been grounded correctly, a neutral bar will not shock you. The reason has to do with the amount of current coming through to the bus bar after it has been used by the load. This is why it’s possible to touch the neutral bus bar without getting shocked.
Once again, this is only assuming the neutral bus bar is within a functional electrical circuit and everything has been grounded appropriately.
If there are any issues in this regard, it can still be dangerous for you to touch any component within that live circuit including the neutral bus bar.
Does Neutral Bar Carry Current?
Yes, a neutral bar does carry current. However, it is a minimal amount as the current will already have been used by the load within the circuit. The neutral bar is between the load and the utility line, which means any current going through it will be weakened.
You should always assume the neutral bus bar carries current when handling it.
This is important as there are layers to this and you have to be careful when handling any type of electrical component including the bus bar.
What Happens If Neutral Is Not Grounded?
If neutral is not grounded, the live current will become dangerous to anyone in contact with it. This is due to the current not flowing through the circuit as expected. In this case, the current can become exposed to metal parts of the circuit making it increasingly dangerous.
It’s essential to double-check each part of the circuit due to this reason.
Whether it is a neutral wire or a neutral bus bar, everything is assumed to be live until the grounding has been verified.
This is the only way those components are not endangering you when power is coming through.
Can you touch the neutral bus bar?
You can touch a neutral bus bar assuming the circuit is correctly grounded. The reason this is possible comes down to the amount of voltage in a current. The current passing through to a neutral bus bar will already have been used by the load. This means the remaining current will be a shell of itself and not hold as much energy.
You are always recommended to shut off the power source when handling anything inside an electrical circuit including the neutral bus bar.
It might not shock you but that is assuming everything is grounded correctly. Do not take a chance in this regard.
