Introduction
Rewiring an entire house may seem like an overwhelming task, but with some preparation and the right materials, it can absolutely be done in a single weekend even on a tight $50 budget. As someone who has personally rewired my 1,500 square foot home in just two days, I've learned a few key tips and tricks to make the process faster, safer, and more affordable.
In this comprehensive guide, I'll walk through everything you need to know to rewire your home yourself, step-by-step. Here's what we'll cover:
Gathering the Right Materials and Tools
The first step is making sure you have all of the basic materials and tools on hand before starting the project. Here's what you'll need:
Materials
- Romex NM-B Electrical Wire - Make sure to get enough 12/2 and 14/2 wire in various lengths to rewire all of your home's circuits. You'll need to calculate the square footage to know exactly how much wire to get.
- Wire nuts - Get a variety pack of twist-on wire connectors in various sizes.
- Electrical tape - Stock up on a few rolls of basic electrical tape which will be used to cover connections.
- Electrical boxes - Purchase new plastic electrical boxes to replace old or damaged ones as needed.
- Wall plates - Buy a multi-pack of new wall plates to install over electrical boxes.
- Circuit breakers - Have spare 15, 20, and 30 amp single-pole circuit breakers on hand for the electrical panel.
Tools
- Voltage tester - This is essential for safely checking wires are dead before working on them.
- Wire strippers - A basic pair of manual wire strippers will be needed to strip Romex wire.
- Screwdrivers - Have both Phillips and flat head screwdrivers available.
- Stud finder - Useful for locating studs to mount electrical boxes.
- Drill - For drilling holes to run wires between floors.
- Ladder - A small step ladder will be handy for accessing the ceiling.
- Headlamp - Wear a headlamp when working in tight spaces or ceilings.
- Safety gear - Wear rubber gloves and eye protection when working with electrical.
Planning the Rewiring
Once you have the needed supplies, it's time to plan out the rewiring project. Here are some key steps:
- Turn off the main breaker - Shut off all power at the main electrical panel before working.
- Map out all existing circuits - Note which rooms or areas are on each circuit in the electrical panel to replicate this in the rewiring.
- Inspect and replace electrical boxes - Look for any damaged existing boxes and buy replacements as needed.
- Decide on new wire routes - Determine the optimal paths to run new wires to each room.
- Have a plan for lighting - Think about how many switches and lights each room needs.
- Consider safety issues - Look for any potential hazards like exposed wiring, water damage, etc.
Running New Wires
Now comes the fun part - running all new electrical wiring throughout the house. Follow these tips:
- Start at the electrical panel - Rewire one circuit at a time starting from the main panel.
- Run to first outlet - Fish the Romex wire to the first receptacle or switch box for that circuit.
- Leave extra length - Always leave some extra wire in case you need to move boxes slightly.
- Use safe techniques - Never nick or damage wire insulation while running wires.
- Staple neatly - Use plastic wire staples to secure wires every few feet in unfinished areas like attics or basements.
- Drill holes mindfully - When drilling holes in studs or joists for wires, avoid penetrating existing electrical, plumbing, etc.
- Connect lights and switches - Wire in all lights, switches, and other devices on each new circuit.
Connecting New Circuits at the Panel
The last stage is connecting all of the new circuit wires to fresh breakers in the main electrical panel:
- Detach old wires - Remove each old circuit's wires from the breakers or fuse box.
- Mount new breakers - Install new appropriately sized breakers for each freshly wired circuit.
- Connect new wires - Attach the new Romex wire for each circuit to the matching new breaker.
- Double check connections - Verify the wire connections are very tight and secure.
- Checkpolarity - Make sure hot and neutral wires are connected to the correct breaker terminals.
- Label everything - Use the old circuit map to neatly label each new circuit at the panel.
Testing and Troubleshooting
Before turning the main power back on, take some time to double check your work:
- Tug wires - Verify all connections are super tight and wires are securely stapled.
- Check for hazards - Scan for any loose bare wires, potential shorts, exposed conductors etc.
- Verify grounding - Confirm all boxes and devices are properly grounded.
- Test with lamp - Plug a lamp into outlets to test for power before using them.
- Inspect thoroughly - Take one final close look at every connection and wire run.
- Flip main breaker - Finally, turn the main breaker back on only after completing all tests.
- Fix issues - If any circuit loses power, methodically troubleshoot to find and fix the problem.
Conclusion
While rewiring an entire house in a single weekend is certainly ambitious, it can absolutely be achieved armed with the right materials, proper planning, safe techniques, and a methodical approach. Just take it one circuit at a time, double check everything, and don't be afraid to call an electrician if you hit any snags. With some diligence and care, you can save thousands on electrical costs by DIY rewiring your home. Just be sure to always put safety first!
