What is flex conduit?
In this regard, what is flex conduit called?
Flexible metallic conduit (FMC, informally called greenfield or flex) is made by the helical coiling of a self-interlocked ribbed strip of aluminum or steel, forming a hollow tube through which wires can be pulled. FMT is a raceway, but not a conduit and is described in a separate NEC Article 360.
Similarly, how long can you run flexible conduit? 250-18 limits flexible metal conduit to 6 ft only for grounding. In lengths over 6 ft, you must install a separate grounding conductor.
People also ask, where can I use flex conduit?
Either rigid or flexible, conduit protects the wires and is used in exposed locations, such as along the exterior surface of a wall. It is also used in unfinished areas, like basements, crawlspaces, and attics, and for surface-mounted installations outdoors.
Can I use flexible conduit outdoors?
Outdoor flexible nonmetallic tubing is strong and watertight, non-corrosive and weighs less. Metal or plastic boxes can be used with nonmetallic conduit. Always run a ground wire when using PVC conduit.
