Choosing Flexible Wire Conduit
If you’re an electrician or are looking to do some DIY wiring, flexible conduit can be a great choice. They can encase wires to protect them from physical damage and the elements, and they’re typically easy to install. Choosing the right type of flexible conduit for your project can be a bit tricky, though. Different types have different raw materials, wall thicknesses and performance features, so it’s important to understand the differences before deciding which one is right for your project.
The first thing you should do is decide what size of conduit you need. This will depend on the number and size of the wires or cables you’re protecting. Ensure that the conduit will fit comfortably and leave room for future expansions or changes in wiring. You’ll also need to determine the level of protection you need. Some conduits are designed to withstand extreme temperatures and weather conditions, while others are more appropriate for residential applications or commercial settings.
Flexible metallic conduit, or FMC, is a common choice for dry environments. It’s made by helically coiling a metal strip that is interlocked together, forming a flexible hollow tube for wires to be pulled through. It’s often used in commercial buildings for electrical motor connections, as well as in underground car parks. It’s not waterproof, but it’s ideal for dry areas where it would be impractical to install EMT or rigid conduit.
PVC coated galvanised steel flexible conduit is suitable for outdoor, commercial and industrial installations where both mechanical protection and moisture resistance are required. Its durable coating shields against corrosion and damage, making it a popular option for use in factory and heavy duty installation settings.
Another popular option is vinyl coated steel flexible conduit, which is suitable for wet environments. It’s a good choice for applications where the wiring is exposed to water, such as irrigation systems, pump stations and fountains. It’s also commonly used in commercial and industrial settings for heating, ventilation, air conditioning and machine tooling. For more details please visit flexible wire conduit
Finally, you can choose a liquid tight flexible nonmetallic conduit (LNFC) for wet environments and hazardous locations. This type of conduit is a good choice for commercial and public spaces, such as train stations, hospitals and shopping centres. It’s fire retardant and emits low amounts of toxic smoke in the event of a fire, which is particularly important for places that are frequented by the public.
When installing flexible conduit, it’s essential to follow the instructions carefully and ensure that all fittings and connectors are correctly attached. You should also ensure that the conduit is sized appropriately for your project and that the installation method is in line with code requirements. Finally, make sure you have the proper tools to cut and bend the conduit if necessary. It’s not recommended to use regular scissors, as they lack the strength and sharpness needed for cutting through metal and thick PVC. Instead, use a conduit cutter, hacksaw or utility knife to achieve precise, clean cuts.
