I have decided to rewire my home's electrical system myself to save money. This is a big project that requires planning, safety precautions, the right materials, and proper techniques. Here is my guide on how I am rewiring my home's electrical system on a budget.
Assessing the Current Electrical System
Before beginning any rewiring project, it is crucial to thoroughly assess the current electrical system. Here are the key steps I took:
-
Check the electrical panel - I opened the panel and inspected the circuit breakers, wires, and labeling. I looked for any signs of damage, wear, or amateur work. This gave me a sense of what I would be working with.
-
Test the circuits - I tested every circuit by turning on all lights and outlets connected to it. I made note of any circuits that seemed faulty, not working properly, or with outlets that sparked. These would need to be fully rewired.
-
Evaluate the wiring - I opened up outlets and switches to view the current wiring. I looked for old fabric-coated wiring or wires that were cracked, damaged, or poorly connected. This type wiring should be replaced.
-
Consider electrical needs - I thought about my family's current and future electrical needs. We plan on installing a hot tub, which will require a dedicated circuit. I want to make sure the rewiring meets all our anticipated electrical demands.
Developing a Rewiring Plan
Once I understood the state of the existing electrical system, I developed a room-by-room rewiring plan.
-
Map out the circuits - I drew up a map showing where each circuit is located and what it powers. This let me plan the best layout for the new circuits.
-
Decide on new circuits - Based on our electrical needs, I determined how many circuits each room required. I grouped rooms with similar needs on shared circuits.
-
Plan circuit routes - I mapped out the path I would run each new circuit, from the electrical panel throughout the house to the endpoints. I chose the shortest routes possible while keeping accessibility in mind.
-
Consider special circuits - I made note of any special circuits, like those for large appliances. These may require thicker gauge wiring and dedicated breakers.
-
Include future needs - I included capacity for future electrical needs like a hot tub, electrical vehicle charger, or workshop. It's cheaper to install now rather than later.
Purchasing the Right Materials
Rewiring a house is a big job that requires a lot of wire and supplies. Here is what I needed to purchase while keeping costs low:
-
Wire - I calculated the total length of wire I would need for the project and bought it in bulk on sale. Solid copper wire is best. I opted for thinner gauges like 14-2 to save money in areas with lighter electrical loads.
-
Breakers - I only bought enough new breakers to replace worn or faulty ones, and for any new circuits I'm adding. Check amperage ratings.
-
Outlets and switches - I bought these in bulk. I stuck with standard models, not fancy decorative ones that cost more. I am reusing existing outlets and switches that are still in good shape.
-
Conduit and boxes - I am using plastic PVC conduit for all my wiring runs as it is lightweight and inexpensive. For boxes, I bought electrical junction boxes in standard sizes.
-
Other supplies - I already had basic supplies like wire strippers, drills, screwdrivers, etc. For safety, I used GFCI outlets in the kitchen, bathroom and all wet areas.
Safety Tips for Rewiring
Working with electrical wiring can be extremely dangerous. Here are some key safety precautions I am taking:
-
Turn off power - I am doing the rewiring with the main power shut off at the panel. I also turn it off and verify with a voltage tester whenever I leave and return to be safe.
-
Wear rubber boots and gloves - I use thick rubber gloves and boots when doing any electrical work to avoid accidental shocks. Safety goggles are also a must.
-
One circuit at a time - I disconnect one circuit at a time and label all wires. This prevents wires from getting mixed up. I also replace only one circuit at a time for simplicity.
-
Use caution drilling - I carefully check for existing wires before drilling into walls and floors. Hitting a live wire can injure or potentially kill.
-
Cover live wires - Any exposed wires are fully wrapped in electrical tape. This prevents accidental contact.
-
Ask electrician if unsure - Although I have wired outlets and switches before, I still consult with an electrician if I am unsure about any aspect of the rewiring. Safety first!
Tips for Rewiring on a Budget
Here are some tips I used to rewire my home's electrical system without spending too much:
-
Shop sales and buy materials in bulk - This saved me 20% or more on most supplies.
-
Consider thinner wire gauges - I could use 14-2 instead of 12-2 in most rooms to save over 25% on wiring costs.
-
Reuse existing switches and outlets - By reusing those still in good condition, I saved big on not buying new ones.
-
Do the labor myself - Doing the installation work myself rather than hiring an electrician saved thousands in labor costs.
-
Stage the rewiring over time - I don't have to rewire my whole house at once. Doing it room-by-room allows me to spread out costs.
-
Only replace what must be replaced - I am not replacing properly functioning circuits or wiring just for aesthetic reasons.
-
Allow for future expansion - Building in capacity for future electrical needs now avoids having to rewire again later.
-
Take safety precautions - I don't cut corners on safety just to save money. Proper gear and precautions are a must to avoid electrocution or fires.
-
Get permits and call for inspections - Doing this ensures the work meets code requirements, giving me peace of mind that it is done safely and correctly.
By following these budget rewiring tips and doing the proper planning, I am confident I can upgrade my home's electrical system myself at a fraction of the cost of hiring an electrician to do it. But safety always comes first!
