Following basic safety protocols is non-negotiable when taking on a DIY rewiring project.

Preparing for the Rewire

Completing preparatory work ahead of time will make the rewiring process smoother:

1. Turn Off Power

The first step is always to shut off power to the area you'll be working on at the main breaker panel.

2. Remove Old Wiring

Carefully extract any existing wiring that will be replaced. Also take out old outlets, switches and hardware.

3. Map out the Project

Diagram where you want receptacles, switches, lighting fixtures etc to map out the new circuitry.

4. Install New Breaker Panel

If upgrading, have an electrician install a new breaker box that can handle your electrical needs.

5. Buy Necessary Materials

Make a list of all the wires, boxes, conduits, outlets and other materials your particular project requires.

Running the New Wiring

The key steps for running new wiring for your DIY electrical rewire are:

1. Cut Power Access Holes

Cut holes in walls and ceilings where wiring needs to pass through using a drywall saw.

2. Run Cable

Run NM electrical cable from the breaker panel through access holes to each outlet or switch. Leave extra length.

3. Mount Boxes

Attach electrical boxes securely in the proper positions for each outlet, switch and light fixture.

4. Connect Wires

Thread the cables into the boxes and connect wires to receptacles, switches etc according to code.

5. Secure Cables

Use cable staples or clips to neatly and permanently anchor the wiring inside the access holes.

6. Insulate Wires

Properly insulate wire connections with electrical tape or wire nuts according to the cable gauge.

7. Ground Wires

Connect ground wires and ensure proper grounding per code. Consult an electrician if unsure.

Thoroughly going through each step results in safe and effective new electrical wiring.
