Run New Electrical Wires

What happens in this clip

Feed the new electrical wire (Romex) through the drilled holes in the studs. Start from the central opening and push the wire through each hole, guiding it to the newly cut openings for the light fixtures. Ensure there is enough slack at both ends for making connections, but not excessive slack that could cause issues within the wall.

What's used

Tools

• Needle-Nose Pliers with Wire Cutters
• Romex Electrical Wire (14/2 with ground)

About the full video

This project provides detailed instructions on how to upgrade a bathroom's lighting by replacing a single, old wall-mounted light fixture with two new, hardwired wall-mounted fixtures. It covers marking the layout, cutting drywall, installing electrical boxes (new work for the main junction, old work for fixtures), running new electrical wiring, making connections, and reinstalling drywall sections.

Step 3 of 7: Run Electrical Wire

Determine the most efficient path to run the electrical cable (e.g., Romex) from the power source (typically a junction box or switch) to each of the cut openings. This may involve running wire through wall cavities, attics, or crawl spaces. Secure the cable using appropriate clips or staples to the framing members, ensuring it is not pinched or damaged. Leave enough slack at each opening to make the electrical connections.
