What is thin wall conduit?

Last Updated: 3rd June, 2020

Intermediate metal conduit (IMC) is a steel tubing heavier than EMT but lighter than RMC. It may be threaded. Electrical metallic tubing (EMT), sometimes called thin-wall, is commonly used instead of galvanized rigid conduit (GRC), as it is less costly and lighter than GRC.

Simply so, what is thin wall EMT?

Electrical Metallic Tubing (EMT) Electrical metallic tubing (EMT), also commonly called thin-wall, is a listed steel raceway of circular cross section, which is unthreaded, and nominally 10′ long.

One may also ask, what is the difference between EMT and rigid conduit? Rigid is a thick wall conduit that is normally threaded. EMT is a thin wall conduit that is not thick enough to be threaded.

Also to know, what are the different types of conduit?

There are seven different types of conduit used commonly in residential and light commercial wiring.

  • Rigid Metal Conduit—RMC and IMC.
  • Electrical Metallic Tubing—EMT.
  • Electrical Non-Metallic Tubing—ENT.
  • Flexible Metal Conduit—FMC and LFMC.
  • Rigid PVC Conduit.

What does LB conduit stand for?

D36. Description: Orbit Industries threaded conduit bodies are commonly used for electrical service entrance wires or as an economical convenience box when extra wire capacity is needed. They are attached to threaded rigid or IMC conduits when a change of direction is required.

Can EMT be buried?

Not all types of conduit can be buried in the soil. EMT (Electrical Metallic Tubing) and flexible “Raintite” are not considered suitable for burial. Aluminum Rigid will corrode away in certain soils, such as clay, or in moist areas. That leaves PVC (PolyVinyl Chloride) conduit as the choice for most do-it-yourselfers.

Does EMT conduit rust?

Typical EMT Type conduit will resist rust for a few years. It is however inevitable that it will rust. On the other hand there have been times when the conduit has rusted on parts of its surface having been exposed to the outdoor elements for one or two seasons.

Is EMT measured ID or OD?

Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS).

OD and Nominal Pipe Size.
Nominal Pipe Size Outside Diameter (inches)
1" 1.315
1-1/4" 1.66
1-1/2" 1.9
2" 2.375

Can PVC conduit be used outdoors?

PVC conduit provides protection for electrical work that is buried underground. Out of the many conduit forms available, PVC conduit is considered best for outdoor applications. Among all conduit types, PVC is lightweight and versatile. PVC conduit is also used for many electrical requirements.

Is electrical conduit measured by ID or OD?

The ID and OD
For instance, a 1-inch rigid conduit will have an ID of 1.063 inch nominal while a 1 inch intermediate metallic conduit will have an ID of 1.12 inch nominal, yet both have the same knockout size of 1.375 inches.

Can plumbing PVC be used for electrical conduit?

PVC pipe can be used in place of PVC conduit if the PVC pipe has been manufactured to meet safety requirements on flame and temperature resistance, but because PVC conduit isn't pressure tested, PVC conduit cannot replace PVC pipe. So, the answer is YES. A PVC pipe can be used for electrical conduit.

What type of conduit can be buried?

The National Electric Code (NEC) sets the required burial depth of electric wire in rigid, non-metallic conduit, such as PVC, at 18-inches. Cable in any conduit, including PVC, that is buried at this depth is not in danger of being severed or disturbed by normal digging.

Do you need conduit in walls?

Smaller cables shall be run either through bored holes in joists or on running boards. So basically if the cable is on the ceiling, it does not require conduit. If the cable is run along walls, it requires some form of protection. This protection can be conduit, or some other form of protection.

Can Schedule 40 PVC be used for electrical conduit?

1.2 Schedule 40 and 80 conduit and fittings
Schedule 40 rigid PVC conduit, elbows, that are specifically marked for underground use are suitable for use underground only by direct burial or encasement in concrete. The UL listing says both 80 and 40 can be used in both above and underground installations.

What is the difference between conduit and pipe?

The basic difference between conduit and pipe is – conduit pipes are used for electrical purposes, but pipes are used for plumbing purposes. Conduit protects the electrical and optical fibres and cables from the external environment. A pipe is used primarily in plumbing and other pressurized systems.

Is EMT allowed in concrete?

Corrosion protection - EMT can be installed in concrete, in direct contact with the earth, or in highly corrosive areas where protected by suitable measures against corrosion. Wet locations - EMT can be used as long as all fittings are corrosion-resistant.

Edyta Bernkopf


Can I use EMT conduit outside?

EMT is identified for use in locations where exposed to physical damage but not 'severe' physical damage. The difference is a matter for interpretation. EMT can be used in wet locations as long as the conduit is galvanized and you use all fittings that are identified for wet locations and protected from corrosion.
