Neutral Bus Bar Full (Solved)

Depending on the electrical setup, it’s possible the neutral bus bar might deal with 100% usage.

This creates a scenario where you have to be diligent about your approach and figure out what needs to be done to add to the setup.

This is essential if the neutral bus bar is full.

If the neutral bus bar is full, it’s best to inspect the existing setup, invest in a gauge wire, connect between the current and new bus bar, and re-test the connection.

It’s always recommended to assess the neutral bus bar to see what your options are. Do not assume it is full until you are sure there is no more space.

This guide will take a look at the steps to deal with a neutral bus bar that is full and how to manage the situation to optimize your setup.

Steps If The Neutral Bus Bar Is Full

1. Inspect The Existing Setup

When setting up a neutral bus bar, you will want to figure out what is going on with the existing setup.

You need a grasp of this to fully understand whether or not it is wise to add a separate neutral bus bar into the setup.

In general, you will know it is full when there are limited screws available to you.

At this point, the only option is going to be to add a separate neutral bus bar that will expand the connection points.

Your goal is to not only see whether or not the neutral bus bar is full but to also make sure there is enough space to add a new one.

Remember that the setup has to be safe for it to work as you want it to.

2. Set Up A Gauge Wire

Now it is time to start working on how you are going to expand the neutral bus bar.

Since you have run out of connection points, the only option is to invest in a new neutral bus bar that will connect to the current one.

If that is the case, you will require a gauge wire.

The gauge wire is going to be the first investment you make and it needs to be a 4a gauge wire for it to work.

Get the right gauge wire and then find a compatible neutral bus bar. It should be the same brand for it to work well.

Do not mix and match.

Once you are ready, you can link the gauge wire to the existing neutral bus bar. This will act as the connecting point between what is already there and the new neutral bus bar.

3. Connect New Neutral Bus Bar

With the new neutral bus bar, you are now going to need to find space to set it up safely.

It should not be getting in the way or anything or exposed to something that will damage the entire circuit.

Your best option is to get a neutral bus bar that is the same brand and then connect it using the gauge wire.

Once you do this, you will want to make sure it is a snug fit.

It should not be loose and/or set up in a flimsy manner.

4. Test The Neutral Bus Bar

You will want to test the neutral bus bar.

It should work when there is something connected to it and you will want to test the entire circuit while doing this.

Not only do you want to make sure the new neutral bus bar is working but also the older one too.

This is how you are going to end up with the result that you want.

Be patient while working on this and you are going to appreciate the nuances that come along with something like this.

Test each connection point.

Final Thoughts

These steps will offer the best results if the neutral bus bar is full.

If a neutral bus bar is full, make sure there are no options available to extend it. If not, invest in a 4a gauge wire, use this to connect a new neutral bus bar to the circuit, and test the circuit for performance.

When done right, the additional neutral bus bar is going to work well and seamlessly.

Remember you will always want to get the same brand to make sure it is compatible. It is not recommended to mix and match unless you are aware of what to look for.

This is how you are going to see the results that you want.

When done well, the neutral bus bar will be effective right away.
