Rigid Steel Conduit — (RSC STEL CONDUIT)
The installation of Rigid Steel Conduit (RSC) is covered by Article 344 of the National Electrical Code® (NEC®). This article is entitled "Rigid Metal Conduit (RMC) and includes all requirements for all rigid metal conduits, including steel, stainless steel, aluminum, and red brass. Information on this STI website covers only rigid steel conduit. You will often see the following acronyms used: RSC (Rigid Steel Conduit), ERSC (Electrical Rigid Steel Conduit), or GRC (Galvanized Rigid Conduit) in place of RMC (Rigid Metal Conduit) in order to differentiate the type of metal used in the product.
Rigid steel conduit (RSC) is a listed threaded metal raceway of circular cross section with a coupling which can be either a standard straight tapped conduit coupling or the integral type. Threads on the uncoupled end are covered by industry color-coded thread protectors which protect the threads, keep them clean and sharp, and aid in trade size recognition. Rigid metal conduit is available in trade sizes 1/2 through 6. Thread protectors for trade sizes 1, 2, 3, 4, 5, and 6 are color-coded blue, trade sizes 1/2, 1 1/2, 2 1/2, 3 1/2 are black, and trade sizes 3/4 and 1-1/4 are red. The nominal finished length of RMC with couplings is 10 feet. Twenty foot lengths are available in some trade sizes.
There are different processes used to provide corrosion protection to rigid steel conduit. Rigid steel conduit can have a primary coating of zinc, a combination of zinc and organic coatings, or a nonmetallic coating (such as PVC). Supplementary coatings can be applied to all three where additional corrosion protection is needed.
Rigid steel conduit is the heaviest-weight and thickest wall conduit. Where galvanized by the hot-dip process, it has a coating of zinc on both the inside and outside. Electro-galvanized rigid conduit has a coating of zinc on the exterior only, with approved corrosion resistant organic coatings on the interior. Rigid conduit with "alternate corrosion protection coatings" generally has organic coatings on both the exterior and the interior surfaces. Galvanized rigid metal conduit (GRC) is non-combustible and can be used indoors, outdoors, underground, concealed or exposed. Rigid steel conduit with coatings that are not zinc-based may have temperature limitations which will be noted on the manufacturer's product label and may not be listed for use in environmental air spaces; consult manufacturers’ listings and markings.
Intermediate Metal Conduit — (IMC STEEL CONDUIT)
The product was developed in the 1970s. Intermediate Metal Conduit (IMC) is a lighter-weight, thinner wall alternative to rigid steel conduit. Covered under Article 342 in the NEC®, IMC is a listed threaded steel raceway of circular cross section with a coupling which can be either a standard straight-tapped conduit coupling or the integral type. Threads on the uncoupled end are covered by industry color-coded thread protectors which protect the threads, keep them clean and sharp, and aid in trade size recognition. IMC is available in trade sizes 1/2 through 4. Thread protectors for trade sizes 1, 2, 3, 4, are color-coded orange; trade sizes 1/2, 1 1/2, 2 1/2, 3 1/2 are yellow; and trade sizes 3/4 and 1 1/4 are green. The nominal finished length of IMC with coupling is 10 feet.
IMC has a reduced wall thickness, when compared to RSC, and weighs about one-third less than RSC. The outside has a galvanized coating for corrosion protection and the inside has an approved organic corrosion-resistant coating. IMC is interchangeable with galvanized rigid steel conduit. Both have threads with a 3/4-inch per foot taper, use the same couplings and fittings; have the same support requirements; and are permitted to be used in the same locations.
Electrical Metallic Tubing — (EMT STEEL CONDUIT)
Electrical Metallic Tubing (EMT), also commonly called thin-wall, is a listed steel raceway of circular cross section which is unthreaded, and nominally 10 feet long. Twenty foot lengths are also available. Covered by Article 358 of the NEC®, EMT is available in trade sizes 1/2 through 4. The outside is galvanized for corrosion protection and the inside has an approved corrosion resistant organic coating. EMT is installed by use of set-screw or compression-type couplings and connectors. It is permitted to have an integral coupling which is comprised of an expanded, "belled" shape of tube on one end with set screws. EMT with integral couplings is available in trade sizes 2 through 4.

 Steel Conduit System


Types and Sizes of Steel Conduit

Steel conduits are manufactured to specifications defined by the British Standards Institute (BS).
Class 4 conduit has a hot dip galvanized finish. It is of heavy gauge with a welded seam. This conduit is suitable for use in external or damp installations.This is the conduit most widely used in this country.


Also manufactured is a solid drawn seamless conduit which is more expensive and only used for special gas tight, explosion proof or flame proof installations.
Conduit is normally supplied in 3 or 3.75 metre lengths and typical conduit external diameters are 16, 20, 25 and 32mm.

Some Advantages of Steel Conduit

·      Affords cables good mechanical protection
·      Permits easy rewiring
·      Minimises fire risks.
·      Can be utilized as the Circuit Protective Conductor.


·      Some Disadvantages of Steel Conduit
·      Under certain conditions moisture is liable to form on the inside wall of the conduit.
·      Expensive compared with some other wiring systems.


3.1 Steel Conduit and Tubing

The wall thickness and strength of steel make RMC, IMC, and EMT the wiring methods
recognized as providing the most mechanical protection to the enclosed wire conductors.
Additionally, a properly installed steel RMC, IMC or EMT system is recognized by the NEC as providing its own equipment grounding path.

3.1.1 Steel rigid metal conduit - RMC (ferrous metal)

Steel Rigid Metal Conduit (RMC) is a listed threaded metal raceway of circular cross section with a coupling which can be either a straight tapped conduit coupling or the integral type Threads are protected on the uncoupled end by color-coded thread protectors which keep them clean and sharp and aid in trade size recognition.
Steel RMC is available in trade sizes 1/2 through 6.Thread protectors for trade sizes 1, 2, 3, 4, 5, and 6 are color-coded blue; trade sizes 1/2, 1-1/2, 2-1/2, 3-1/2 are black, and trade sizes 3/4 and 1-1/4 are red. The nominal finished length of RMC with coupling is 10 feet (3.05m). Longer or shorter lengths with or without coupling and threaded or unthreaded are permitted. Steel RMC can have a primary coating of zinc, a combination of zinc and organic coatings, or a nonmetallic coating with or without zinc (such as PVC). Other supplementary coatings can be applied to all three where additional corrosion protection is needed.

Special installation practices and tools are generally required for working with PVC-coated products. These practices are covered in Section 6. Steel RMC is the heaviest-weight and thickest-wall steel conduit. Where galvanized by the hot-dip process, it has a coating of zinc on both the inside and outside. Electro-galvanized rigid has a coating
of zinc on the exterior only, with corrosion-resistant organic coatings on the interior. Steel RMC with alternate corrosion protection generally has organic coatings on both the exterior and the interior surfaces. Galvanized RMC has no temperature limitations and can be used indoors, outdoors, underground, concealed or exposed. RMC with coatings that are not zinc-based sometimes has temperature limitations or is not listed for use in
environmental air spaces; consult manufacturers’ listings and markings.

3.1.2 Intermediate metal conduit – IMC (ferrous metal)

Intermediate Metal Conduit (IMC) is a listed threaded steel raceway of circular cross section with a coupling which can be either a straighttapped conduit coupling or the
integral type Threads are protected on the uncoupled end by color-coded thread protectors which keep them clean and sharp and aid in trade size recognition. IMC is available in trade sizes 1/2 through 4. Thread protectors for trade sizes 1, 2, 3, 4, are color-coded orange; trade sizes 1/2, 1-1/2, 2-1/2.3-1/2 are yellow; and trade sizes 3/4 and 1-1/4 are green. (See Table 1 for Metric Trade Size Designators.) The nominal finished length of IMC with coupling is 10 feet (3.05m). IMC has a reduced wall thickness and weighs about one-third less than RMC. The outside has a zinc based coating and the inside has an organic corrosion-resistant coating. IMC is interchangeable with steel RMC. Both have threads with a 3/4-inch per foot (1 in 16) taper; use the same couplings and fittings; have the same support requirements; and are permitted in the same locations.


3.1.3 Electrical metallic tubing - EMT (ferrous metal)

Electrical Metallic Tubing (EMT), also commonly called thin-wall, is a listed steel raceway of circular cross section which is unthreaded, and nominally 10 feet (3.05m) long (see Figure 3). The outside corrosion protection is zinc-based and the inside
has an organic corrosion-resistant coating. Trade sizes are 1/2 through 4. .EMT is installed by use of set-screw or compression-type couplings and connectors. EMT is permitted to have an integral coupling which is comprised of a “belled” end of the tube with set screws .


Elbows are bent sections of conduit or tubing to change raceway direction or bypass obstructions. IMC and RMC elbows are threaded on each end. Elbows of the correct type and dimensions are an important element of the raceway installation. Factory-made elbows in both standard and special radius are readily available for all sizes of steel
RMC, IMC, and EMT. Elbows with integral couplings are available in trade sizes 2-1/2 through 4. Specialized large radius elbows, often referred to as “sweeps,” are also available. They are custom ordered to solve various installation problems.Some typical uses of sweeps are to facilitate easier wire pulling, install conduit in limited or
geometrically difficult space, provide specific stubup length, or enhance protection of communication or fiber optic cables during pulls. Physical dimensions of factory-made elbows for RMC, IMC, and EMT vary between manufacturers. When installing factory elbows for a job, being aware of this variability can avoid installation problems. Always measure to be safe. To order factory elbows, you need to specify the raceway
type, trade size, and angle of bend. If ordering a special radius elbow, the radius will also have to be specified.

3.2.2 Nipples

A nipple is a short length of conduit or tubing material which is used to extend the system. Nipples are used between conduit and items such as (but not limited to) fittings, boxes, and enclosures or between two boxes, two enclosures, etc. When nipples are used to extend a conduit run to an enclosure, box, etc., the percentage wire fill requirements shown in Chapter 9, Table 1 of the NEC apply; for example, 40-percent fill for three
or more conductors. When a nipple is installed between boxes, enclosures, etc. and the nipple does not exceed 24 inches (610 mm), wire fill is permitted to be 60%.Factory-made RMC nipples are threaded on both ends and are readily available in all sizes in lengths 12 inches (305 mm) and under. Longer lengths are available by special order or may be fieldfabricated.


3.2.3 Couplings

Each length of steel RMC and IMC is furnished with a coupling on one end. Additional threaded couplings are readily available for all conduit sizes. Steel RMC and IMC with an integral coupling are available in trade sizes 2-1/2 through 4. This is a coupling which permits joint make-up by turning the outside coupling rather than the conduit (see
Figure 4). EMT with an integral coupling is available in trade sizes 1-1/4 through 4. The EMT has a belled end with set-screws.For threadless fittings for use with RMC, IMC, and EMT
