Rewiring a home can seem like a daunting task, but with the right planning and a few clever tricks, it doesn't have to be. As a homeowner embarking on a rewiring project, I've discovered some brilliant hacks that have made the process much easier and more affordable.
Understanding Home Wiring Systems
Before getting into the nitty gritty of rewiring, it's important to understand the basics of home electrical systems. Here's a quick overview:
The Main Service Panel
This is the central hub where all the electricity entering your home is distributed. It contains circuit breakers that shut off power to different circuits if they become overloaded. The main service panel is usually located outside or in the basement.
Breaker Boxes
Also known as subpanels, these provide access to individual circuits and route power to different areas of the home. Check your breaker boxes to identify which circuits need to be rewired.
Electrical Wiring
This refers to the cabling running through walls, ceilings and floors distributing electricity. In modern homes, you'll typically find 3-wire cables made of copper inside plastic or rubber insulation.
Receptacles and Switches
These are outlets and switches found throughout your home controlling lights and power for devices and appliances. Your rewiring project will involve replacing these.
Mapping Out Your Home's Circuits
Before tearing into walls to rewire, it's important to create a detailed map of your home's existing circuits. Here are some tips for mapping circuits:
-
Check the main service panel - circuit breakers should be labeled with which rooms or areas they control.
-
Turn breakers off one at a time and see which outlets/lights stop working in your home.
-
Use a tracing tool to identify wires hidden behind walls. A neon circuit tester is handy for this.
-
Mark each circuit on a floor plan and label outlets and fixtures corresponding to their circuits.
Having an accurate circuit map is invaluable when rewiring to ensure proper power distribution.
Investing in Quality Materials
When selecting new wiring, splurge on high-quality copper cables rather than cheaper aluminum alternatives. Copper is more durable and less prone to hazardous overheating.
For outlets and switches, spend a little more for commercial grade models that can withstand frequent use. They really do last longer.
Also, choose insulated staples to secure new wiring rather than metal staples which can damage wire sheathing. Spending a tad more on the right materials now will pay off for years to come.
Taking Advantage of Existing Wiring
One brilliant trick when rewiring is using existing wiring when possible. For instance, if replacing an outlet in the middle of a circuit, you may be able to disconnect it from the old wiring and splice it to the new wires.
Just be sure to inspect existing wiring thoroughly for any cracks, burns or defects before incorporating it into your new system. Taking advantage of intact old wiring can save a lot of time and hassle.
Running New Wiring Through Wall Voids
When running new circuit wiring through finished walls, one of my go-to tricks is using existing voids to avoid major demolition. I probe walls with a wire hanger bent in a narrow “L” shape to find internal cavities left from old plumbing, ductwork, etc.
Feeding wire through these voids allows installing new circuits without tearing up walls in a laborious process. Just be diligent about fire-caulking any penetrations when you’re done.
Employing Specialized Tools
Upgrading your toolbox with a few specialized rewiring tools can expedite the process and produce cleaner results. Here are some worth investing in:
-
Cable staple gun - Allows securely fastening wiring to joists and studs in tight spaces.
-
Flexible drill bits - For drilling neat holes through framing to run wires from room to room.
-
Cable puller - Uses leverage to easily pull new wiring through long runs in walls and ceilings.
-
Cable stripper - Quickly strips sheathing off wires without damaging conductors.
The right specialty tools make tricky rewiring steps much simpler and cleaner for DIYers.
Learning Basic Electrical Skills
While some homeowners want to DIY their entire rewiring project to save money, others don't feel comfortable working directly with electrical systems.
In the latter case, it can be helpful to learn just enough basic electrical skills to assist an electrician with simple tasks. For instance:
-
Learn how to safely turn off power and verify it's off before work begins.
-
Become familiar with electrical terminology so you understand what's being discussed.
-
Know how to provide basic assistance like drilling holes or pulling cables.
Picking up a few basic electrical skills allows you to lend a hand during a rewiring project without getting in over your head. And this can help reduce the costs of hiring an electrician full-time.
Rewiring a home seems intimidating to many homeowners, but armed with the right preparation and hacks, it's very much a DIY-friendly project. Follow proper safety measures, be patient, and you'll have a sparkling new electrical system before you know it. Let me know if you have any other brilliant rewiring hacks I should try!
