Installing conduit in an existing wall can be a challenging task, but it is certainly possible with the right tools and techniques. Conduit is a protective tube used to house electrical wires, cables, or other utilities, providing a safe and organized pathway within walls. Whether you are adding new electrical outlets, upgrading your home’s wiring, or incorporating new technologies, installing conduit can be a beneficial solution. In this article, we will explore the process of installing conduit in an existing wall, highlighting the necessary steps and considerations.
Assessing the Wall:
Before beginning the installation process, it is important to assess the wall to ensure it is suitable for conduit installation. Take into account various factors such as the wall’s material, thickness, and any plumbing or existing electrical wiring present. Conducting a thorough evaluation will help you determine the feasibility of installing conduit within the wall.
Choosing the Right Conduit:
There are several types of conduit available, including rigid metal conduit (RMC), electrical metallic tubing (EMT), and flexible conduit. Each type has its own advantages and installation requirements. Consider factors such as the wiring material, environmental conditions, and code regulations in your area when selecting the appropriate conduit for your project.
Gathering the Necessary Tools and Materials:
To install conduit in an existing wall, gather the following tools and materials:
- Conduit of your choice
- Wall-mounted conduit boxes
- Conduit couplings
- Non-metallic cable connectors
- Fish tape or wire pulling tool
- Drill with appropriate-size hole saw bit
- Screwdriver
- Wire cutter/stripper
- Pencil or marker
- Measuring tape
Creating a Pathway:
To install the conduit, you will first need to create a pathway through the wall. Begin by determining the best route for the conduit, ensuring it avoids any obstacles, such as studs or plumbing, that could hinder the installation. Use a stud finder to locate the position of wall studs.
Next, mark the locations where the conduit will enter and exit the wall. Measure and mark the appropriate height for conduit boxes. These boxes will serve as junction points where the conduit connects to electrical outlets or switches.
Drilling Holes:
Using a drill with an appropriate-size hole saw bit, carefully drill holes at the marked entry and exit points. Ensure the holes are sized to accommodate the chosen conduit. Be cautious when drilling, especially if there are existing electrical wires or plumbing in the wall, to prevent any accidental damage.
Thread the Conduit:
Attach a fish tape or wire pulling tool to the end of the conduit and feed it through the entry hole until it reaches the exit point. This process may require some patience and finesse, especially if there are obstacles within the wall. If necessary, obtain assistance from another person to guide the conduit as you push it through.
Connecting the Conduit:
At the exit point, install a conduit coupling to connect additional conduits, if needed. Then, secure the conduit to the wall using appropriate straps or clips. Repeat this process if you have multiple conduits to install.
Once the conduit is securely in place, attach conduit boxes at the junction points, using screws to fasten them to the wall. Carefully insert your electrical wires or cables into the conduit, ensuring they are properly secured.
While installing conduit in an existing wall can be a complex process, it is achievable with careful planning and attention to detail. By following the steps outlined in this article and adhering to local building codes and regulations, you can successfully install conduit to enhance your electrical system and accommodate new technologies. Remember to seek professional assistance if you are unsure or unfamiliar with electrical installations to ensure safety and proper compliance.
