Low Voltage and EMT Conduit

Being able to install EMT conduit in structured cabling jobs is a necessity now for low voltage contractors. Gone are days of expecting electricians to have your pathways pre-installed.

Low Voltage and EMT Conduit
  1. Low voltage contractors need to be able to install EMT conduit for several reasons. First and foremost, EMT conduit provides a protective housing for low voltage cables, helping to prevent damage and interference from outside sources. Without proper protection, cables can be exposed to moisture, temperature fluctuations, and physical damage, which can degrade their performance and lead to costly repairs.
  2. In addition to protecting cables, EMT conduit allows low voltage contractors to organize and manage cables more efficiently, reducing the risk of tangles and disconnections. Additionally, conduit can help to create a more professional and aesthetically pleasing appearance for the cabling installation, which can be important in commercial or public settings.
  3. EMT conduit is also a requirement in many local building codes and regulations for low voltage cabling installations, and failure to comply can result in penalties or legal action. By being able to install EMT conduit, low voltage contractors can ensure that their installations are up to code and avoid any potential legal issues.
  4. Furthermore, EMT conduit is available in a variety of sizes and can be bent to fit different configurations, providing low voltage contractors with flexibility in their installation options. This allows them to adapt to different installation environments and achieve the best possible performance for their clients.
  5. By being proficient in EMT conduit installation, low voltage contractors can deliver high-quality and reliable installations to their clients, while also ensuring compliance with regulations and providing professional and organized installations. The installation process of EMT conduit involves determining the route of the conduit, choosing the right size of conduit, preparing and bending the conduit, installing the conduit, pulling and connecting the cables, and testing the network to ensure proper functionality.

  1. Determine the route of the conduit: This involves planning the path of the conduit and identifying any obstacles or challenges that may need to be addressed. You can use a measuring tape and a level to determine the length of the conduit needed and ensure it is level. You should also ensure that the route is safe to work on and that the conduit will not be exposed to any hazards.
  2. Choose the right size of conduit: The size of conduit you need depends on the number and size of the cables you'll be running through it. In general, the larger the cables, the larger the conduit you'll need. Common sizes of EMT conduit include 1/2-inch, 3/4-inch, and 1-inch. You should consult local building codes and regulations to ensure you are using the right size of conduit.
  3. Prepare the conduit: To prepare the conduit, you'll need a conduit cutter or hacksaw to cut the conduit to the desired length. You should then use a conduit reamer or deburring tool to remove any sharp edges or burrs from the ends of the conduit. This will prevent any damage to the cables when you pull them through the conduit.
  4. Bend the conduit (if necessary): If the route of the conduit requires it to be bent, you'll need a conduit bender to create the bends. It's important to use the correct size of bender for the size of conduit you're using. You should also follow the manufacturer's instructions to ensure you're making the bends correctly.
  5. Install the conduit: This involves sliding the conduit into any fittings or connectors that you need to use. You should also ensure that the conduit is securely fastened to the wall or ceiling using conduit straps or other types of support. It's important to follow local building codes and regulations when installing the conduit.
  6. Pull the cables: Once the conduit is installed, you can start pulling the cables through the conduit. You'll need a cable pulling tool to make the process easier. It's important to take your time and be patient, and to ensure that you don't pull the cables too tightly, as this can damage the insulation and affect the performance of the cables.
  7. Connect the cables: Once the cables are in place, you should connect them to any patch panels, switches, or other networking equipment that you're using. You should also ensure that the cables are properly labeled so that you can easily identify them later on.
  8. Test the network: Finally, you should test the network to ensure that everything is working properly. You can use a network tester to check the performance of the cables and ensure that there are no issues with connectivity or data transfer. You should also test for any interference or noise that may affect the network's performance.

In summary, to install EMT conduit in a structured cabling project, you'll need to determine the route of the conduit, choose the right size of conduit, prepare the conduit, bend the conduit (if necessary), install the conduit, pull the cables, connect the cables, and test the network. By following these steps and using the right tools, you can ensure that your conduit is installed correctly and that your network is protected and functioning properly.
