How does a Subpanel Works?

A subpanel is a panel that is installed in order to provide additional electrical service. The subpanel gets its power from the main panel, and it then distributes that power to other circuits. This can be helpful if you need more space for your electrical devices or if you want to add an extra circuit.

How To Connect a Subpanel? Step-By-Step

If you are installing a subpanel, then you will need to connect it to the main panel. This can be done by using a wire that is the same size as the wire that is used for the main panel. You will also need to make sure that the wire is rated for the amperage of the subpanel.

Let’s get into the steps you need to take for connecting a subpanel.

1. Mount the Subpanel Into The Wall

The first step is to mount the subpanel into the wall. You will need to make sure that it is in a location where you have access to the main panel.

Once the subpanel is in place, you can start wiring it. The wire connections should be made at the top of the subpanel.

You will need to connect the wire to the lugs that are provided. These lugs should be tightened so that they are secure.

If you are using a copper wire, then you will need to use a wire connector. This will ensure that the connection is secure and will prevent corrosion.

Now, you can move on to the next step.

2. Plan the Route

Now that you have mounted the subpanel, it is time to plan the route of the wire. You will need to make sure that the wire can reach from the subpanel to the main panel without any problems.

You should also take into account things like bends and turns in order to avoid creating a mess. Once you have planned the route, you can start running the wire.

If you are running the wire through a wall, then you will need to use wire staples. These staples will keep the wire in place and will prevent it from being damaged.

As you run the wire, make sure that it is not touching any other wires or metal objects. This can create a fire hazard. Once the wire is in place, you can move on to the next step.

3. Connect The Wire To The Main Panel

The final step is to connect the wire to the main panel. You will need to remove the cover of the main panel and then find a spot where you can make the connection.

Once you have found a spot, you can loosen the screws on the main panel and then install the wire connector. Make sure that the wire is secure before you tighten down the screws.

Now, all you need to do is reattach the cover of the main panel and then test your subpanel.

Reasons For Installing Subpanels

There are a few reasons why you might want to install a subpanel.

1. It Easily Controls Multiple Devices

If you have a lot of devices that are drawing power, then a subpanel can be helpful. This will allow you to easily control all of the devices without having to overload the main panel. It eases your job when you are running a woodworking business since you will be able to connect multiple devices easily.

A subpanel can also help if you have multiple devices that are running on different circuits. It can be difficult to manage all of these circuits if they are all running through the main panel.

The subpanel will allow you to easily control each circuit and prevent them from being overloaded.

2. No More Space on Main Panel

The main panel can only handle so many devices. If you have reached the limit of what the main panel can handle, then a subpanel can be a good solution.

This will allow you to add more devices without having to worry about overcrowding or overloading the system.

A subpanel is also a good option if you want to add a circuit for a new appliance. This will free up space on the main panel so that you can use it for other devices.

3. Greater Proximity

If you have devices that are located far away from the main panel, then a subpanel can be a good option. This will allow you to have closer proximity to the devices so that you can easily access them.

A subpanel is also a good option if you want to add a circuit for a new appliance. This will free up space on the main panel so that you can use it for other devices.

Conclusion

Installing a subpanel can be a great way to improve the function of your electrical system. It can help you to better control multiple devices and circuits.

It can also provide you with more space on the main panel. If you are thinking about installing a subpanel, then be sure to follow the steps that Whole Sale Power Tools has outlined in this article.
