Updating the electrical wiring in your home can seem like a daunting task, but with the right planning and techniques, it can be accomplished efficiently and safely. Here are some brilliant yet rarely used methods to rewire your home yourself.
Assess and Plan Your Rewiring Project
Before beginning, take time to thoroughly assess your current electrical system and decide what you want to accomplish with the rewiring.
-
Make a list of problems you want to correct like outdated wiring, insufficient circuits, or inadequate lighting.
-
Decide which rooms or areas you want to focus the rewiring project on. Rewiring your whole house at once can be overwhelming. Consider tackling it one room or circuit at a time.
-
Research local electrical codes to ensure any new wiring meets the required standards. Have an electrician review your plan if possible.
-
Map out a detailed plan marking all circuits, fixtures, switches, and outlets. Include measurements for wire lengths.
-
Calculate your total costs for materials and tools. Rewiring a room yourself can save thousands over hiring an electrician.
Safely Prepare for Rewiring
Before touching any wiring, make sure to shut off power at the main circuit breaker. Test wires with a non-contact voltage tester to be sure they are dead.
-
Remove existing switches, outlets, and fixtures from walls that you'll rewire. Label wires as you disconnect them to keep track.
-
Inspect the existing wiring for damage and replace any unsound wires. Assess if you also need to upgrade your electrical service panel.
-
Have fire extinguishers on hand and keep a first aid kit readily available in case of emergencies.
-
Cover floors, furniture, and valuables with drop cloths to protect them from dust and debris.
Fish Wires with Versatile Tools
Fishing wires through walls can be a frustrating task. Utilize versatile tools to save time and hassle when pulling new wires.
-
Use long drill bits to drill pathways between wall studs to thread wires through. Install conduit if needed.
-
Try a wire pull system like a wire pull rod with attachments to grip wires and pull them through openings.
-
Use wire pull lubricant for long wire runs to reduce friction for an easy pull.
-
Consider renting or buying a fish tape - a flexible steel cable used to snake wires through walls. It's extremely useful for long wire runs.
-
Have a strong fiberglass rod available to push wires through for shorter runs or around obstacles.
Connect Wires Securely
Connecting wires properly helps ensure safe and long-lasting electrical connections.
-
Strip wires neatly using a sharp wire stripper calibrated for proper depth. Don't nick the metal conductor.
-
Pre-twist wires together with pliers before inserting into outlets, switches or wire connectors.
-
Use push-in clamps in the back of new outlets/switches to connect wires securely without wire nuts.
-
Verify ground wires are sufficiently long to connect to outlets safely. Use pigtails if needed.
-
Wrap connections securely with electrical tape for additional strength and protection.
Finish the Job Like a Pro
Pay careful attention to details when completing your rewiring project.
-
Confirm all connections are tight and then test outlets and switches to ensure proper function.
-
Replace insulation neatly and seal openings with caulk for safety and aesthetics.
-
Secure new wires and boxes properly so they don't shift within walls over time.
-
Label all circuits clearly in the electrical panel and add notes on any unique wiring.
-
Have an electrician inspect your work thoroughly before re-energizing the system to catch any mistakes.
With the right planning and methods, rewiring your home is an achievable project for a dedicated DIYer. Follow safety precautions, utilize specialized tools, and pay attention to detail for best results. The improvements and cost savings from DIY home rewiring make it a worthwhile endeavor.
