Is conduit simply conduit, and duct just duct, that we use for inside and outside use. Some people call it the same, and some people find it difficult, so let's see some truths about ducting wires.
Usually, the shapes and dimensions are the same, and very often, the non-metallic conduit and duct are composed of polyvinyl for making fiber, copper, and coaxial-cable installations compatible. "Some ta are compose of polyethylene as it is flame-retardant, and metal is often used inside and outside,"
This fact is highly debatable as some people think that ducting wire created for indoor and outdoor applications is composed of a different material. They are fundamentally made of the same material, but usually, the companies manufacture PVC products in electrical, communications, plumbing, irrigation, hardware, and sewer markets. And literally, there is no distinction between outside and inside conduit. The only difference between the two is of application and the way people pronounce it. When used inside, it's called conduit or tubing, and in the case of external application, they are called duct banks.
Facts are hidden from general awareness
Some underground duct offers only a route for cable and with little or no protection and the conduit provides a route along with physical security. The lightweight material is always the best choice for external routing rather than physical safety. Most outside-plant ducts t usually don't have Underwriters Laboratories listing for indoor application because they are too explosive for indoor use.
Electrical ducts should always use electrical conduits that are recognized for use underground and other raceways around for security process, which means it should be listed for underground use, embedded in earth or concrete as per the law. This is another amazing fact about ducting wires or conduits that people don't know; However, every single china ducting wire supplier and manufacturer knows this, but still, this fact is away from consumer awareness.
