What do you call flexible conduit?



Flexible metal conduit (FMC) is also called “Greenfield,” after the name of its inventor. It has a spiral construction that makes it flexible so it can snake through walls and other structures.

What is flexible PVC conduit called?

Electrical conduit can be rigid (metal, PVC or thermosetting resin) or flexible (metal (FMC), liquid tight metal (LFMC) and liquid tight non-metallic (LFNC). All conduit comes in a variety of sizes and there are limitations on how each type may be used.

What is another name for flexible metal conduit?

These tubes are usually made of either steel or aluminum. The steel is harder and protects the interior cables better, but aluminum is much lighter. There are three basic styles of flexible metal conduit. The common style, called flexible metallic conduit (FMC), is made of a single strip of steel or aluminum.

What are 3 types of conduit?





Electrical Conduit Types

  • Rigid Metal Conduit (RMC)
  • Electrical Metallic Tubing (EMT)
  • Intermediate Metal Conduit (IMC)
  • Flexible Metal Conduit (FMC)


What is electrical conduit called?

Metal. Rigid metal conduit (RMC) is a thick-walled threaded tubing, usually made of coated steel, stainless steel or aluminum. Galvanized rigid conduit (GRC) is galvanized steel tubing, with a tubing wall that is thick enough to allow it to be threaded.

What is flexible non metal conduit?

Non-metallic conduit is a versatile product that has a variety of applications for indoor and outdoor locations. Non-metallic conduit is used in fixture whips, data centers, electric signs and outdoor lighting, HVAC, pool and spas and locations with exposure to sunlight and weather conditions and more.

Is PVC conduit flexible?





PVC conduit is also used for many electrical requirements. This product is flexible and durable and resists corrosion.

What are the types of flexible conduit?

How many types of conduit are there?

The two main types of metallic conduit and raceway are rigid and flexible. Rigid conduit offers solid protection. Flexible metal conduit allows for bends and twists without using extra hardware. Prewired conduit, or armored cable, offers an all-in-one solution with the wires already running through it.

Is EMT conduit flexible?

EMT (Electrical Metallic Tubing) conduit is a non-flexible, non-corrugated raceway designed specifically for electrical cables. Our EMT conduit is made of galvanized steel to prevent chipping, cracking and peeling.



What is flexible metal conduit?

Flexible metal conduit (FMC) has a spiral construction that enables it to snake through walls and other structures. FMC protects electrical wiring in commercial and industrial buildings. Liquidtight flexible metal conduit (LFMC) is a special type of FMC that has a plastic coating.

Where is a flexible conduit needed?

Flexible conduit systems are generally used to encase wires, helping to reduce the risks of electrical hazards, such as electrocution. Liquid-tight conduits, for instance, are covered in a watertight plastic coating that in combination with the IP67 rated liquid-tight fittings, protects cables against water damage.

What is PVC conduit used for?

Electrical conduit PVC’s main purpose is for use in electrical systems as a housing for electrical wires or cables. PVC conduit is often used in underground and wet location applications where electrical cables need to be protected.

What are the different types of flexible nonmetallic conduit?

  • Flexible Metal Conduit. Galvanized Steel. Gal Steel, Water Proof (PAG Series) …
  • Braiding Conduit (EMC/EMI) Stainless Steel Braiding.
  • Flexible Electrical Conduit. Anti-static Type.




What is the other type a non-metallic conduit?

Types of non-metal conduit



These include: Rigid non-metallic conduit (RNC) – a non-metallic, unthreaded, smooth-walled type of tubing, often made from PVC and used in wet locations. Electrical non-metallic tubing (ENT) – a thin-walled corrugated tubing that is moisture-resistant and flame retardant.

What is the difference between flexible conduit and MC cable?

Flexible metal conduit (FMC) is commonly called “Greenfield.” The main difference between MC cable and FMC is that FMC doesn’t have the insulated wires pre-installed; you have to pull them through instead.

Where can I use flexible PVC conduit?

This Flexible, Non-Metallic PVC Liquid Tight conduit, commonly referred to as NM Liquid Tight, flexible conduit, Non-Metallic PVC, Flex PVC and PVC Electrical Conduit is perfect for use in multiple applications for electrical, telephone, cable, HVAC, Refrigeration, landscape lighting and more.

Where can ENT conduit be used?

WHERE CAN I USE ENT? ENT can be used in place of EMT, Rigid Galvanized Steel, AC or MC/ cable and NM cable. Just refer to Section 362.10 of NEC (see Section 10 of this manual.) ENT can be used in residential, commercial, schools, condominiums, apartments and industrial applications.

What is ENT used for?

ENT specialists treat conditions such as ear infection, hearing loss, dizziness, ringing in the ears (called tinnitus), ear, face, or neck pain, and more. Nose (rhinology)—Our noses facilitate breathing by helping to keep out potentially harmful dirt, allergens, and other agents.

What does ENT stand for in electrical?

25. 1.1 Electrical Nonmetallic Tubing (ENT), is designed to replace EMT, flexible metal conduit or other raceway or cable systems, for installation in accordance with Article 331 of the National Electrical Code, other applicable sections of the Code, and local codes.

Can you bury ENT conduit?

Article 362 of the 2002 National Electrical Code, Uses not Permitted, prohibits ENT from being direct buried.
