Types of Electric Cable Casing
Electric cable casings come in various forms, each suitable for specific applications. Understanding these types will help you select the right one for your needs.
BX Cable
BX cable, also known as metal-armored cable or type AC, is a popular choice for both indoor and outdoor use. It consists of insulated wires bundled together and protected by metal sheathing. BX cable is particularly important when grounding is required due to its metal casing, which can be connected to a grounding system.
Vigo Electric Cable Casing
Vigo Electric Cable Casing, manufactured by RFL Group, is designed to protect and route electrical wiring in buildings. This PVC casing offers fire protection and is suitable for both residential and industrial applications. Its flexibility makes it easy to work with during installations.
Casing and Capping Wiring
This traditional wiring method involves placing PVC-insulated wires in plastic casings and covering them with caps. Casing and capping wiring is commonly used in residential settings for low-voltage applications. It provides an organized and aesthetically pleasing way to manage wiring.
Conduit
Conduit is a more robust option, available in metal or PVC. It provides excellent protection for electrical cables against environmental factors, making it suitable for commercial and industrial applications. Metal conduits offer superior strength, while PVC conduits are lightweight and resistant to corrosion.
Cable Trays
Cable trays are used to support multiple cables in industrial settings. They can be made from metal or fiberglass and are designed to allow for proper ventilation. While cable trays can consume more space, they provide a practical solution for managing large-scale cable installations.

Installation Techniques for Electric Cable Casing
Installing electric cable casing requires careful planning and execution. Here are some best practices to ensure a successful installation.
Step 1: Planning
Begin by planning the layout of your electrical wiring. Consider factors such as the location of outlets, the number of wires, and the type of casing you will use. Ensure that your design complies with local electrical codes and standards.
Step 2: Selecting the Right Tools and Materials
Gather all necessary tools and materials before starting. For BX cable, you may need wire cutters, a cable stripper, and grounding tools. For PVC casings, ensure you have a saw for cutting and adhesive for securing joints.
Step 3: Preparing the Area
Clear the installation area of any obstructions. Ensure that the walls and surfaces are clean and ready for mounting the cable casing. Mark the locations where the casing will be installed.
Step 4: Installing the Cable Casing
Follow the manufacturer’s instructions for installing the cable casing. For BX cable, attach the metal sheath to the wall using appropriate fasteners. For PVC casings, use adhesive to secure the pieces together, ensuring a snug fit.
Step 5: Running the Wires
Carefully run your electrical wires through the installed casing. Ensure that you leave enough slack for connections and avoid kinking the wires. Use wire ties or clips to secure the wires within the casing.
Step 6: Finalizing the Installation
Once all wires are in place, cap the casing securely. For BX cables, ensure grounding connections are properly made. Test the installation to confirm that everything is functioning correctly before closing up any walls or surfaces.
