Whenever your project involves extending or adding an electrical circuit, electricians will need to run new wires from the power source to the desired endpoint. This process, commonly known as "pulling wires," can vary in complexity. It might entail pulling just a few feet of cable to an additional outlet or extending dozens of feet to create an entirely new circuit connected to the main service panel.

 

Pulling wire can often be the most challenging and time-consuming aspect of an electrical project. Initially, you'll need to locate the existing electrical wires within your walls, typically using a magnetic or electrical stud finder. These wires will be running through drilled holes in the wall studs. The standard height for running electrical wires in walls is typically 16 to 18 inches above the floor, aligned with the wall's outlets.

 

The most intricate work arises when running electrical wires between floors in a house, such as from a remodeled second-story space to a basement service panel. This may involve removing and patching drywall in the existing part of the house. To minimize damage, you can cut a channel in the finished wall surface, ensuring the removal of as little drywall as possible.

​

In many jurisdictions, tasks involving the installation and connection of wiring necessitate obtaining a building permit, along with an onsite inspection. Occasionally, a homeowner may be permitted to undertake such work themselves, provided it's within their own residence. Sometimes, acquiring a permit may require completing a brief homeowner's electrical exam.

 

Skipping the permit and inspection procedures is ill-advised. These protocols are in place to guarantee the work's safety and to ensure that the wire gauge can handle the amperage load, while also verifying that cables are appropriately routed through the studs.

​

​Installing NM cable for new or extended circuits is relatively straightforward, but connecting outlets, switches, and circuit breakers necessitates specific expertise. If you're not entirely confident in your abilities, it's recommended to enlist the services of an electrician for the final connections. Moreover, local codes may mandate that only licensed electricians perform work on the service panel. Additionally, for lengthy or intricate cable runs, it's advisable to consult an electrician.
