How Are Electrical Wires Run Through Walls?
Wiring an electrical system can be a daunting task for homeowners. However, knowing how the wires are run in walls can help you plan your project and avoid potential problems hiring someone or doing your own wiring. In this blog post, we’ll look at how electrical wires are run in walls.
1. Through Fishing
This is where electricians drill small holes in the wall and then feed the electrical wires through it using a “fish tape.” The fish tape is used for fishing electrical wires through spaces where there is no other access. The fish tape is fed through a small hole in the wall and then retrieved by hooking it onto the end of the wire. Once the wire is in place, the electrician will seal up the spot, so it is not visible.
2. Using Conduits
A conduit is a tubing system used to protect and route electrical wiring on walls of buildings. The wiring involves running electrical cables or wires through a metal or plastic tube, which helps to provide additional protection against fire and damage. The conduit is typically mounted on walls, or electricians will drill a hole through the wall or ceiling where the conduit will be run.
3. Through Trunking
Trunking involves the running of electrical wires through a single channel. The channel, or trunk, is usually made of metal or plastic and is fixed onto the walls. The channels are typically arranged in a grid pattern, with the cables running parallel.
4. Through Cabling
Cabling is where the electrician will run the electrical wire along the wall’s surface. Once the wire is in place, they will use clips or tape to secure it to the wall. The cables can also be run through drilled walls.

DIY vs. Pro: Staying Safe When Fishing Wires
Running cable through walls can expose hidden hazards like live junctions, damaged insulation, or overloaded circuits. If you encounter aluminum wiring, frequent breaker trips, or warm outlets, stop and have a licensed electrician evaluate the circuit before you continue.

When to Call a Licensed Electrician
Running cable can look straightforward until you hit structural members, unknown circuits, or outdated panels. If you encounter brittle insulation, crowded top plates, mystery junctions, or frequent breaker trips, pause and bring in a pro. We’ll evaluate the route, load, and code details so the job is safe and tidy.
