How to Re-Wire Your Home Using Centuries-Old Techniques
Introduction
Re-wiring a home can seem like a daunting task, but it doesn't have to be. With some careful planning and by using centuries-old techniques, you can successfully re-wire your home yourself.
Reasons to Re-Wire
Here are some of the main reasons you may want to re-wire your home:
Safety
-
Old wiring can present serious fire and electrocution hazards. Upgrading to modern electrical codes improves safety.
-
Faulty wiring like loose connections can arc and spark, igniting fires. Re-wiring ensures secure connections.
-
Overloaded circuits from too many appliances can overheat wires. Re-wiring allows for extra circuits.
Functionality
-
Upgrade to grounded outlets throughout the home for surge protection.
-
Add additional circuits and outlets where needed for convenience.
-
Allow for installation of modern appliances and devices that old wiring can't handle.
Efficiency
-
New higher-gauge wires reduce energy loss from resistance, saving money.
-
Separate circuits for high-draw appliances like AC units increases efficiency.
Planning Your Re-Wiring Project
Careful planning is crucial when taking on a re-wiring project. Here are some key steps:
Consult an Electrician
-
Discuss your plans with a licensed electrician to ensure compliance with codes.
-
They can identify any issues with your existing wiring to address.
-
An electrician can also handle any re-wiring you don't feel comfortable doing.
Map Out Your Existing Wiring
-
Diagram the locations of outlets, switches, appliances, and your electrical panels.
-
Note any double-tapped breakers or overloaded circuits to be improved.
-
Verify your main service size to ensure it's sufficient.
Develop a Re-Wiring Plan
-
Decide which circuits need upgrading or separating.
-
Plan any new wiring routes avoiding plumbing, ductwork, etc.
-
Select appropriate wire gauges and types for each circuit.
Purchase Necessary Materials
-
Buy the required wires, outlets, boxes, tools, etc. for the project.
-
Ensure breakers and panels will accommodate added circuits.
-
Label everything clearly to stay organized during the re-wiring.
Using Old-World Wiring Techniques
Once planned out, it's time to re-wire your home using proven old-world techniques:
Running Wires Through Walls
-
Cut narrow channels into walls to route wires instead of fully opening them up.
-
Use long flexible drill bits to bore holes through framing when necessary.
-
Carefully notch holes where wires enter boxes without weakening structure.
Securing and Protecting Wires
-
Anchor wires with insulated staples when running them through open spaces.
-
Keep wires separated from sharp metal edges using plastic guides as needed.
-
Use metal protective plates where wires pass through studs and joists.
Connecting Wires to Outlets and Switches
-
Join wires to devices using screw or clamp terminals instead of risky backstabbing.
-
Wrap connections with electrical tape for insulation and protection from vibration.
-
Make pigtail connections to link wires with wire nuts or crimp connectors.
Testing Circuits
-
Confirm each run's integrity by powering up and checking outlets.
-
Verify grounding on all upgraded ungrounded outlets for safety.
-
Check for shorts by confirming no breakers trip when energized.
Completing the Upgrade
Once the re-wiring is complete, there are just a few more steps:
-
Have an electrician inspect the work and ensure it meets code.
-
Update your home's wiring diagram for future reference.
-
Properly dispose of any old wiring that has been removed.
-
Flip the breakers and start enjoying your new safe and robust electrical system!
Re-wiring a home is very rewarding when done properly using time-tested techniques. Take all precautions, get help when needed, and your home will have electrical power suited for the decades to come.
