How to Rewire Your Home without an Electrician and Save Thousands
Introduction
Rewiring a home can seem like a daunting task, but with proper planning and safety precautions, it is possible for a dedicated DIYer to complete it successfully without professional help. The advantages of rewiring your home yourself include saving thousands of dollars in electrician fees, gaining in-depth knowledge of your home's electrical system, and the satisfaction of completing a major home improvement project on your own.
In this comprehensive guide, I will walk you step-by-step through the entire home rewiring process from start to finish. With the right materials, adequate preparation, and by following important safety guidelines, you can rewire your home safely without an electrician and save a substantial amount of money.
Gather Necessary Materials and Tools
Before beginning any work, you need to ensure you have all the necessary materials and tools on hand. At a minimum, you will need:
-
Electrical wire - 14/2 and 12/2 NM cable for 15 amp and 20 amp branch circuits. Pay attention to wire gauge needed for longer wire runs.
-
Wire stripper - For removing sheathing and cutting wires to length.
-
Wire connectors - To join wire ends together.
-
Electrical tape - For covering connections.
-
Circuit breakers - Appropriate amperage based on wire size.
-
Junction boxes - For housing connections and splices.
-
Conduit - EMT or PVC to protect wiring between boxes.
-
Fish tape - For running wires through walls.
-
Voltmeter - For testing connections.
-
Other hand tools - Hammer, saw, drill, ladder, drywall tools, etc.
Consult electrical code books for your region to determine exact specifications for materials prior to purchase. Having all required materials on hand before starting will make the process smoother.
Create a Plan
Rewiring a house requires careful planning and organization. Take time to:
-
Familiarize yourself with the National Electrical Code requirements.
-
Educate yourself on proper electrical safety procedures.
-
Develop a basic floor plan highlighting all locations requiring new wiring and fixtures.
-
Detailing a basic circuit mapping diagram indicating breaker amperages, wire runs, and connected devices.
-
Research permits required in your region and have inspections scheduled in advance.
Thorough planning and adherence to electrical code requirements will ensure the new wiring in your home meets all safety regulations and passes inspection.
Turn Off Power and Remove Old Wiring
Safety should be the number one priority. Before touching any wiring:
-
Shut off the main breaker and verify power is off at the panel.
-
Disconnect the grounding wire from the bus bar in the service panel.
-
Once power is confirmed off, carefully remove old wiring and devices.
-
Take pictures of existing wiring for reference as you work.
Turning off all home power and working on dead wiring is extremely important for preventing electrical shock or electrocution. Never work on wiring that may still be live.
Install New Wiring and Components
With the power off, you can now begin installing the new wiring system:
-
Start by mounting the new electrical panel and reconnecting the grounding wire.
-
Run circuit wires from the panel to each outlet and switch box location. Use conduit where allowed by code for protection.
-
At boxes, make proper connections using cable clamps and wire connectors.
-
Anchor wires to boxes using cable clamps. Maintain neat wiring.
-
Use voltmeter to test for continuity before reconnecting power.
Follow your circuit mapping diagram to connect wires to the appropriately sized circuit breakers. Use cable ties and wire management clips to keep wiring organized at the panel.
Connect Fixtures and Devices
With the wiring in place, it's time to install:
-
Wall outlets and switches into their boxes. Follow manufacturer directions.
-
Permanently mounted light fixtures, fans, etc.
-
Any other hardwired appliances or equipment like stoves, HVAC systems, etc.
-
Label breakers clearly for each circuit.
-
Verify ground connections are properly secured.
Double check connections at each box and device before moving to the next. Consult wiring diagrams as needed for unfamiliar connections. Meticulous attention to detail is crucial.
Restore Power and Test
You're almost done! To finish:
-
Verify all connections are complete and boxes properly closed. Remove any unused wires.
-
Close up the panel and ensure it is properly sealed. Double check your wire organization.
-
Restore main power, turn breakers on one by one, and test operation of each outlet, switch and fixture.
-
Visually inspect all connections for problems and test GFCI outlets.
-
Consult local codes for any required inspections and remediation.
Once everything is tested and confirmed to be working properly, you can relax knowing you just completed a major electrical project safely without the expense of an electrician!
