We’ll cover everything from gathering the necessary tools and supplies, to performing all the steps needed for installation. Let’s get started!

Gather the Necessary Tools and Supplies



Before starting any project, it’s important to make sure you have all the necessary tools and supplies. For replacing a light fixture junction box, you’ll need the following items:


  • A replacement junction box

  • Phillips head and flathead screwdrivers

  • Voltage tester

  • Electrical tape

  • Wire cutters/strippers

  • Needle nose pliers



Make sure you have all these items on hand before attempting to replace the junction box; they will make the process a lot easier.

Turn off Electricity and Disconnect the Wiring



The first step when replacing a light fixture junction box is to turn off the electricity to the area you’re working in. Make sure that all power is off before you proceed with the project. Once you’ve ensured the power is off, it’s time to disconnect the wiring from the old junction box.

Grab your Phillips head and flathead screwdrivers and use them to remove the screws attaching the wires to the box. At this point, you should also use a voltage tester to make sure that all power has been shut off before going any further.

Remove the Old Junction Box



Now that the wiring has been disconnected, it’s time to remove the old junction box. To do this, grab your flathead screwdriver and start unscrewing the screws that are holding the box in place. Once they’re loosened up, take the box off the wall and set it aside.

Install the New Junction Box



Next, it’s time to install the new junction box. Grab your new box and tighten up the screws that hold it in place. Make sure that it is securely fastened to the wall and that there is no movement when pushed lightly.

Connect the Wiring to the New Box



Now that the new box is installed, it’s time to reattach the wiring. This can be done by using your electrical tape to tape the wires together, then wrapping them around the screws on the new box. Make sure to use the correct screw for each wire and that they are all secure.

Once the wires are connected to the new box, it’s time to turn the electricity back on. Before turning the power back on, make sure the wiring is properly connected to the new junction box and that all screws are tightened.

Final Thoughts



Replacing a light fixture junction box isn’t difficult, but it does require a certain level of attention and care. As long as you follow the steps outlined above and use the right tools and supplies, you should be able to get your light fixtures functioning properly again in no time.
