Create a plan - Map out a detailed plan for running new wire to each location needing power. Include switch legs, junctions, and any special wiring needs.
-
Label circuit breakers - To match existing outlets and switches, take photos of the breaker labels. Shut off power.
-
Remove old wiring - Carefully extract existing wires from boxes and conduits without damaging anything that will be reused.
-
Inspect boxes and conduits - Verify existing boxes and conduit runs are in good condition to reuse and up to code.
-
Purchase materials - Buy all of the magnet wire, electrical tape, boxes, conduit, and accessories you will need for the project.
-
Prepare work area - Set up a well lit, organized, and comfortable work station where you will prepare the wire segments.
-
Schedule time - Rewiring a whole home will take days or weeks. Set aside enough time so you can work carefully without rushing.
-
Arrange inspections - Contact your local building department to schedule rough-in and final inspections of your rewiring work.
With thoughtful preparation, you can tackle the rewiring of your home efficiently, safely, and up to code. Take the time to properly plan and set up your project.
Step-by-Step Process
Once you are fully prepared, you can get started with the rewiring using this step-by-step process:
Cutting and Stripping Magnet Wire
-
Measure circuits - Measure the length of each wire run from outlet to switch to junction using a tape measure. Add extra length as needed to account for bends and box connections.
-
Cut wires - Using sharp wire cutters, cut the magnet wire to the measured lengths. It is better to cut pieces too long rather than too short.
-
Strip ends - Use wire strippers to remove 3/4" of insulation from both ends of each wire segment. Take care not to nick the copper.
-
** Repeat** - Follow the same steps to cut and strip all the magnet wire needed for the entire rewiring project.
Connecting and Splicing Wires
-
Attach grounds - Inside boxes, attach ground wires to ground screws or clips first, using pigtails when needed. Verify ground continuity.
-
Connect outlets and switches - Attach hot wires to brass screws and neutral wires to silver screws. Follow diagrams precisely.
-
Join splices - Where required, connect multiple hot or neutral wires together in a junction box using wire nuts. Twist tightly.
-
Make switch legs - Run additional hot wires from switches to outlets controlled by the switch. Keep all neutral connections continuous.
-
Check polarity - Test each connection with a multimeter and polarity tester to ensure proper wire orientation.
All conductors should be solidly and safely connected with no exposed copper.
Insulating and Bundling Wires
-
Insulate splices - Cover all wire nuts and splices with electrical tape. Wrap tightly to fully seal. This prevents shorts.
-
Bundle circuits - For multi-wire branch circuits sharing neutral, use tape to bundle associated hot and neutral wires together.
-
Affix labels - In junction boxes, use tape to securely label each wire with its circuit number for easy identification.
-
Dress wires neatly - Neatly position and route wires inside boxes so devices can be installed easily.
-
Install box covers - Attach covers carefully to avoid pinching or crimping wires. Leave accessible until inspection.
The wires should now be fully prepared and ready for devices, fixtures, and covers to be installed.
