The use of electrical conduit is a practical process to make sure the electric wires installed in a home or office are given proper protection. The flexible style of conduit is the easiest to work with compared to alternatives like rigid plastic or metal. The flexible conduit does have the downside of not being so strong and gives less protection. But, for the do-it-yourself enthusiast working at home, the flexible material is mostly favored because of its ease of use.
Here are four types of flexible electrical conduit:
Flexible metallic conduit (also referred to as FMC) is a practical choice for the large construction projects, such as building the underground car park. This type of conduit relies on interlocking metal coils to create a long tube that lets the wires pass through. By interlocking the individual pieces it is possible to create a very flexible material. It is practical for the installation protects that take place in a dry environment, but should be avoided if there is a risk of any water penetration.
Flexible metallic tubing
The flexible metallic tubing (FMT) is made to give great flexibility and comes with a metallic tube-like design. It is really easy to route or shape to fit the most difficult areas. For this reason it is great to use on the do-it-yourself projects where it is preferable to not join multiple pieces of conduit together. Also, this type of tubing does not come with any form of waterproof protection.
Liquid Tight Flexible Metal
The liquid tight flexible metal conduit (LFMC) is a versatile choice that is not only effective at protecting the wires from damage, but also gives reliable waterproof protection. In order to give the waterproofing protection, the conduit is coated with a special jacket that simply fits over the top of the metal. This means the LFMC is great to use in any environment, including those areas that may experience issues with damp.
Liquid Tight Flexible Non-Metallic
The liquid tight flexible non-metallic conduit (LNFC) is a reliable option for a wide range of applications. It is built to be very hard-wearing and protective with the ability to give protection from water and flames. Plus, certain LNFC can be manufactured with multiple layers to give extra strength. This is the most practical type of conduit to use in locations that may be seen as potentially hazardous.
Overall, by using the right type of conduit it is possible to safely install the wiring and know that it is well protected for the long-term.
