Whether replacing faulty wiring or updating old wiring, rewiring projects could seem scary. Here are a few tips to help with the process. Always use safety precautions and remember it’s best to consult with a certified experienced technician.
- Appropriate tools and clothing
Tools with rubber-insulated handles should always be used to absorb shock. Also, invest in a reliable current tester. Wear appropriate clothing and keep long hair away from your face. Ensure you have proper eye protection and use caution when working on a ladder or in a tight space.
- Ensure the right power has been cut off
Always cut the electric power before starting the rewiring. You can turn the power off from the main switch in the circuit panel or just turn off the electrical loop that you’re working on, but always use the current tester to make sure the line is dead before starting work.
- Evaluate your current situation
Now take a closer look at your wiring system, as other issues may need to be addressed first before rewiring. A Mister Sparky technician can help you with updates to the wiring or replacing the electrical box if needed. If you want to run any other cables or wires, this is a good time to incorporate that work in too. Make sure any additions fit within the county code and you have all necessary permits. A Mister Sparky technician can also help with questions you may have about current code compliance regulations.
- Remove old wiring
After you have identified the problem areas, a certified technician should take a look at it before you begin the rewiring. This can save you money and time working on wiring that may not need to be replaced. You don’t want to remove every piece of sheetrock since this will create more work for you when covering up the wiring. When you’ve identified the wires you’d like to replace, try to remove them leaving the good wiring in place. Removing old wiring could be difficult, since wiring that is stapled to the joists and wallboards could be in the way. To make this task easier, cut the wire at both ends, and run the new wire through without pulling out all of the old wiring.
- Start rewiring
If possible, you should rewire through the attic. Use extreme caution when drilling holes through cross beams or walls to avoid existing electrical lines. Add any lines that will split off to additional outlets or fixtures by installing a junction box mounted to a joist. Staple wiring to nearby joists where you can access it. Attach the new wires to electrical outlets in the proper locations. For light fixtures, match up the wires, including the ground wire, and use electrical tape to wind the wires together before capping them.
- Finally, check if it works
First double check all circuits to ensure you are connecting them to the correct breaker. Always label your breakers immediately to avoid confusion. Once your wiring is complete from the outlet to the breaker box, test your system and call in a Mister Sparky technician before covering up access points. Our technicians will ensure your wiring is correctly installed and code compliant.
