When selecting the correct size for your Flexible Metal Conduit (FMC), consider the outer diameter of the Electrical Cables and wires you are using, as well as the number of cables you plan to run through the conduit. Additionally, if your installation includes multiple bends or turns, a larger conduit may be required to facilitate wire pulling and to minimise tension on the cables during installation. If you need guidance on which size conduit is best for your needs, get in touch, and we will discuss your options. We stock Steel Conduit Sizes: 10mm, 12mm, 16mm, 20mm, 25mm, 32mm, 40mm, 50mm, 75mm, and 100mm, ensuring we have an option for your Electrical Wiring Application
