Wiring a home can seem like an intimidating task, but with some planning and budget-friendly materials, I was able to rewire my home safely and affordably. In this comprehensive guide, I will walk through all the steps I took to upgrade my home's electrical system on a tight budget.
Researching and Understanding Home Electrical Systems
Before beginning any electrical project, it's crucial to understand how home electrical systems work. Here's a quick overview of the key components:
-
Service panel/breaker box - This is the central hub that divides and directs electricity to different circuits in the home. It contains circuit breakers that shut off power to individual circuits if they become overloaded.
-
Main service line - This is the heavy duty cable that runs from your home to the utility pole outside. It connects your home electrical system to the main power supply.
-
Main breaker - This is the master shutoff switch found at the top of your breaker box. It allows you to cut power to the entire home.
-
Branch circuits - These are the individual circuits that deliver power to specific rooms or zones in your home. Each circuit is protected by its own breaker.
-
Receptacles and switches - Outlets and switches are installed at various points along the branch circuits to provide electrical access. The circuits are connected in parallel, not in a loop.
-
Grounding - A grounding system sends stray electrical current into the earth, preventing shocks and fires. Proper grounding is a must for safety.
To size your home's electrical service correctly, you'll need to calculate the total load in amps that your home requires across all circuits. A licensed electrician can help with this process.
Creating a Home Electrical Plan
Before purchasing any materials, it's wise to map out a home electrical plan. Here are some tips:
-
Evaluate how your home is currently wired and what you want to change.
-
Decide where you need additional lighting, switches, or outlets.
-
Note the amperage rating of major appliances so you size circuits correctly.
-
Plan where you will place the service panel and how circuits will be routed through the home.
-
Ensure all wiring and devices meet the electrical code for your region, especially for kitchens, bathrooms and outdoor areas which have higher safety standards.
-
Consider smart home upgrades like motion sensors, programmable thermostats, video doorbells and smart switches. These can be easily incorporated into your plans.
Don't take chances with electrical safety. If your plans are complex, consult a licensed electrician to review your home electrical design. They can ensure appropriate materials andcircuit ratings are specified.
Buying Electrical Supplies on a Budget
Once you have a home electrical plan, it's time to purchase equipment and wiring. Here are my top tips for saving money on electrical supplies:
-
Buy wire in bulk spools rather than pre-cut lengths - it's significantly cheaper. Use a wire stripper to cut and strip to desired lengths. Buy multiple gauges for different uses.
-
Purchase refurbished breakers and panels from reputable suppliers. They offer certified products at nearly half the cost.
-
For budget receptacles and switches, stick with simple styles and basic colors like white or ivory rather than premium finishes.
-
Use PVC conduit for exposed wiring runs rather than costly metal varieties. PVC holds up well outdoors.
-
Consider used lighting fixtures and lamps from thrift stores or clearance sales to save. Just replace any old wiring first.
-
Buy generic electrical boxes without built-in clamps or brackets to save a few dollars per box. Use separate clamps instead.
With some deal hunting and compromise on styles, you can furnish an entire home electrical system for thousands less than buying everything new.
Safely Running and Connecting Wires
When it's time to start the wiring work, safety should be the top priority:
-
Turn off power at the main breaker before starting, and use a non-contact voltage tester to confirm it's dead.
-
Protect wires by running them through conduit. For indoor walls, use flexible plastic conduit like ENT tubing.
-
Label both ends of each wire run so you know which breaker it connects to.
-
Use cable staples every few feet when running wires vertically in open walls and diagonally across joists in basements or attics.
-
Leave 8-10 inches of extra wire in boxes for easy connection and slack.
-
Match wire colors to the appropriate hot, neutral and ground terminals for each receptacle and switch.
-
Install GFCI outlets in bathrooms, kitchens, garages and outdoor areas for protection from shocks.
Follow all electrical codes for your region, and have inspections done before concealing any wiring. Taking it slow and being meticulous reduces any safety risks and electrical headaches down the road.
Saving on Labor Costs
One of the biggest costs with home electrical work is hiring an electrician for installation labor. But much of the basic wiring like running cables and adding receptacles can be DIYed by a homeowner with some electrical knowledge. Here are tips to take on work yourself while minimizing risks:
-
Only take on what you're fully comfortable doing. More complex tasks like installing a new service panel are best left to the pros.
-
Read through the full instructions before starting any electrical project. Watch online tutorials for guidance.
-
Use a voltage tester to regularly check wires are dead when working. This detects live current.
-
Work slowly and methodically. Rushing leads to dangerous mistakes.
-
Label all wires and terminals clearly for your own reference.
-
If you get stuck or overwhelmed, call an electrician for advice rather than guessing.
-
Always have an electrician do the final hookups and inspection before flipping the main breaker back on.
By doing preparatory work like running cables yourself, you can greatly reduce the total labor charges and still benefit from an electrician's expertise where it's needed most.
Completing the Project Safely
Once all the new wiring is installed and connected properly, there are a few final steps to wrap up the project:
-
Seal any holes and conduit openings with fireproof caulk or foam to maintain fire rating.
-
Use blank electrical plates to cover unused boxes where you've run wiring for future use.
-
Properly terminate all unused wires with wire nuts and cable clamps. Do not leave bare wires exposed.
-
Attach cover plates to all junction boxes to protect wiring.
-
Ensure all circuits are properly labeled at the breaker panel.
-
Turn the main breaker back on and test all outlets, switches and appliances.
-
Walk through the home flipping switches and outlets while looking in the breaker box for tripped breakers, which may indicate shorts.
Taking precautions during the final testing process ensures your new electrical system functions properly and safely without issues down the road.
Conclusion
Rewiring or upgrading a home's electrical system does not have to break the budget. With smart planning, buying supplies strategically, taking on DIY labor when possible, and focusing on safety, I was able to upgrade my home's wiring for thousands less than a full professional rewire. And nothing beats the satisfaction and cost savings of tackling electrical projects yourself. Just be sure to get licensed electrician input whenever in doubt.
