Introduction
Rewiring your entire home may seem like a daunting task, but with the right planning and preparation, it can absolutely be accomplished in a single weekend. As a licensed electrician with over 15 years of experience, I have rewired numerous homes in just 2-3 days.
In this comprehensive guide, I will walk you through every step needed to rewire your entire house safely and efficiently in one weekend.
Gather Your Supplies
Before getting started, you'll need to stock up on the necessary supplies. Here's what I recommend having on hand:
- Electrical wire - Have plenty of 12/2 and 14/2 NM electrical wire on hand. Calculate the square footage of your home and buy 20% more wire than that.
- Electrical boxes - Stock up on electrical boxes, including junction boxes, old work boxes, and exterior boxes.
- Wire strippers - A good pair of manual wire strippers is essential.
- Voltage tester - This lets you safely check that power is off before working.
- Basic hand tools - Have screwdrivers, wrenches, pliers, and wire cutters ready.
- Ladder or scaffolding - For accessing ceilings and high wall areas.
- Headlamp - Frees up both hands for working.
- Electrical tape - For sealing connections.
- Wire nuts - For joining wires together.
- Circuit breakers - Have extra breakers on hand for the new circuits.
With all of these supplies ready, you can knock out the rewiring quickly and efficiently.
Shut Off Power and Remove Old Wiring
Before touching any wiring, shut off power to the entire home at the main breaker. Use a voltage tester to confirm power is off.
Next, go through the entire house and remove all of the old wiring. Take note of where each wire is running as you disconnect and pull them out. Removing the old wires first gives you a clean slate to work with.
Safely dispose of the old wires according to local regulations. Many recycling centers accept copper electrical wire.
I recommend having a helper during this process to speed things up. Just be cautious when working together and communicate clearly.
Map Out Your New Circuit Plan
With the old wires gone, now you can map out your new circuit plan. Grab your blank panel directory and sketch out where you want each new circuit to run.
Here are some tips for planning your new circuits:
- Use 15 amp circuits for lighting and outlets.
- Use 20 amp circuits for major appliances like refrigerators and dishwashers.
- Don't overload circuits. Limit to 10-12 outlets per 15 amp circuit.
- Have dedicated circuits for heavy appliances like air conditioners.
- Include circuits for any new additions like a home office.
Spend time thinking through your circuit plan. This will make the rewiring go smoothly and prevent issues down the road.
Run Your New Wires
Now the fun part begins - running all of your shiny new electrical wires!
I recommend starting with the lighting circuits first. Run 14/2 NM wires from the planned locations for switches up into the ceiling electrical boxes. Continue running wires to connect all of the ceiling boxes where lights will go.
For outlet circuits, run 12/2 NM wires from your breaker panel to the outlets following your circuit map. Make sure to stagger wires across breakers to balance the load.
I like to label each wire with masking tape as I run them. For example, "Circuit 1", "Circuit 2" so you know which breaker it will connect to. This keeps everything organized.
Have your helper feed the wires while you pull them through holes and secure them. Work systematically from room to room for the cleanest installation.
Install Your Electrical Boxes and Devices
As you finish running wires to each location, start installing your electrical boxes and devices.
Use old work boxes when you need to cut into drywall to install a new box. Measure carefully so boxes are neatly aligned.
For lights, install exterior boxes on the ceiling with the wires poking out. Later you'll connect the light fixtures.
For outlets, mount your junction boxes and attach the receptacles to the wires. Follow proper polarity - black wire to brass, white to silver.
Finally, install any needed switch boxes and dimmers according to your lighting plan.
Take it step-by-step and before long you'll have shiny new electrical boxes marching across your ceilings and walls!
Connect Your Wires to the Panel
This is the home stretch! With all of your wires run and devices installed, now it's time to connect everything to the new circuit breakers.
I like to start with the 110v circuits on the main breaker panel. Carefully organize and label the wires coming in from each circuit.
Connect the black hot wire to the breaker terminal and the white neutral wire to the neutral bus bar. Add a ground wire to the ground bus bar as well.
With your helper, have one person in the panel and one poking wires through. Communicate clearly which circuit you're connecting.
Follow your circuit plan and connect each wire to the appropriately labeled breaker. Take it slow and steady here for safety.
Once all of your 120v circuits are connected, do the same process with any 240v appliance circuits you may have.
Add Your Finishing Touches
Almost done! With all your wiring completed and connected, now you can button things up:
- Install light fixtures and appliances on their new circuits.
- Patch any drywall holes or damage neatly.
- Attach covers on the breaker panel and junction boxes.
- Caulk exterior boxes to seal against moisture.
- Clean up thoroughly - sweep, vacuum, and tidy up.
- Label your new panel directory clearly.
Take pride in your workmanship throughout the finishing process. Thoroughly clean up any mess and repair any damage.
Restore Power and Test
It's time for the moment of truth!
With your finishing touches complete, carefully restore power to the panel. Turn on breakers one at a time and walk through testing each circuit:
- Check all lights and switches function properly.
- Test outlets with a lamp to make sure power is live.
- Verify appliances and devices work on the correct circuits.
If something doesn't work, verify the wire connections. The wires may just need a twist or two to make a solid connection.
With all your hard work, the new circuits should be humming along smoothly. But take the time to methodically test everything. Catching any issues now is much easier than later!
Congratulations - relish in the satisfaction of completing a full home rewiring in just one weekend.
Summary
While rewiring an entire house in 2-3 days requires diligence and hard work, it can absolutely be tackled by a motivated DIYer. The key is thorough planning, methodical execution, and rigorous testing.
Follow these steps and tips:
- Stock up on all needed supplies before starting.
- Turn off power and remove old wiring completely.
- Map out new circuits based on your needs.
- Run new NM cables room-by-room.
- Install boxes and devices as you go.
- Carefully connect wires to new breakers.
- Finish up with covers, fixtures, and repairs.
- Restore power slowly and test all circuits.
Take breaks as needed and get a helper for running wires. Be safe by confirming power is off before working.
With the right preparation and determination, you can have a completely rewired home by the end of the weekend. The new electrical system will provide safe, reliable power for years to come.
