How to Install a Junction Box

A junction box is an aluminum box or plastic enclosure box used to cover the electrical wires. The box is can used mounted to walls, flat surfaces.

An electrical junction box contains the connection, also known as a splice, of two or more cables. These cables must be secured to the box using cable clamps or conduit fittings.

 

Here, we will provide a guide on how to install an electrical junction box. But first, let's know the dangers of an incorrect installation.

 

The Dangers of Incorrectly Installing a Junction Box

Many business owners install junction boxes themselves, but there are some dangers of improperly installing junction box. All boxes must be installed according to the Electrical Code. Following this code is essential to protecting you and your property. For instance, it's not a good way to overfill your junction box with too many wires. Having too many wires inside the box can lead to overheating and issues with short-circuiting. But it can also lead to an electrical fire.

 

Step 1: Choosing the Correct Box for Your Needs

It's essential to choose the right junction box for a successful installation. A junction box installed outdoors will require waterproof function.

 

Another factor to consider is the size of the box you need. A junction box need have enough space for the number of wiring connections. A small box can install two cables but no more than this. A large box can install four to six cables.

 

If you don't know which size to choose, it's best to choose a large one for a successful installation.

 

Step 2: Prepare for Box Installation

Before you start installation process, turn off the power to the circuit you are working on. This will ensure that you are working safely.

 

Step 3: Gather All Necessary Devices

You will need specific equipment and materials to install your box. Let's see what you'll need to get started.

 

Equipment

Non-contact voltage tester

Hammer

Screwdriver

Pliers

Drill-driver and screwdriver tip

Wire strippers

 

Materials

Code-approved electrical box

Wood screws

Cable clamps

Wire connectors

 

Step 4: Mounting Process

Before mounting junction box, you will need to separate the wires at their current splice. Be sure to loosen the cables if necessary. This allows to make space for the junction box.


Step 5: Prepare Clamps for Cables

Insert the threaded end of the clamp through one of the holes, and secure the clamp inside the box using the ring-shaped nut. finally, tighten the nut with pliers.


Step 6: Fixed Cables

To fixed cables secure, tighten the screws on the clamps. Be sure not to tighten them too much, as this can cause damage.

 

Step 7: Put the Wires Together

Once the wires are secure, it's time to join them together. check if all wires have been successfully put together. by lightly tug on each wire to see how secure they are.


Step 8: Finish Installation

Finally, carefully put the wires into junction box. Enclose everything with box, and fixed it using two screws.

 

A junction box is necessary when you have an electrical connection because all connections must be enclosed properly.

Remember, never start touching wires unless you are certain that no voltage is coming from them. If you are unable to follow the steps, it's best to hire a professional who can complete the process for you.
