The term “electrical conduit” refers to

to sturdy tubing or other types of enclosures used to protect and provide a path for individual electrical wire conductors.

Conduit is usually required where wires are exposed or where they may become damaged.

The conduit can be made of metal or plastic and may be rigid or flexible.

All pipes are installed with compatible fittings (couplings, elbows, connectors) and electrical boxes, and are usually made of the same or similar materials.

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

• Rigid Metal Conduit – RMC – IMC – EMT – FMC – LFMC – PVC

But let’s get to know our type of this product which is EMT

EMT Electrical Metal Tubing

Another example of rigid electrical conduit is EMT (Electrical Metal Tubing), which is most often made of galvanized steel but can also be aluminum.

EMT is also called “thin-wall” conduit because it is thin and light in weight, especially compared to RMC

EMT is rigid but can be bent with a simple tool called a conduit bender.

EMT installs with couplings and fittings that are secured with screws or compression-type anchors.

The tubes themselves are not threaded like RMC and IMC.

Common sizes for EMT include 1/2 inch, 3/4 inch, and 1 inch.

It is commonly used for running exposed indoor wiring in residential and light commercial buildings.

If installed outside in exposed locations, it must be installed using special weatherproof fittings

the description :

Thin-walled conduit, or Electrical Metal Tubing (EMT), is a graded steel conduit of circular cross-section.

• EMT (thin-wall) conduit is available in commercial sizes from 1/2″ to 2″.
• Protected from corrosion from the outside and from the inside.
• EMT Conduit shall be installed by use of the specified compression or thread type couplings and connectors.
• An EMT conduit is permitted to have an integral coupling at one end with a set screw.
• EMT (Thin Wall) conduit with integrated couplings is available in various commercial sizes.

Features:

• Inside and outside it provides enhanced protection against corrosion, thus, metal-to-metal contact and galvanic protection against corrosion are provided.
• Manufactured from high strength steel and welded by electric resistance welding process.
• The outer surface has a clear post-galvanized coating to provide additional protection against corrosion.
• The inner surface provides a smooth and continuous path for easy and hassle-free wire drawing.
• Both surfaces are crack-free and smooth.
• Excellent ductility, providing uniform bending, and cutting in the field.

Light metal pipes with IMC thread:

• Metal conduit, or IMC, is a rigid steel electrical conduit designed for outdoor exposure and robust connections.
• It is specially designed to protect insulated electrical conductors and cables.
• It does a similar job to the Rigid Metal Conduit (RMC), but weighs about a third less.
• By using IMC in any permitted areas, you can eliminate the need for heavier walled conduit.

IMC Channel Basics

• IMC conduit is coated with a hot-dip galvanized exterior and a special anti-corrosion coating on the interior to extend the life of the conduit.
• Common duct sizes range from 1/2 inch to 4 inches in diameter.
• IMC conduit is threaded to ensure secure connections.
• Installation usually requires large pliers or pipe wrenches.
• The IMC can be cut using pipe cutters or a band saw, but you must file the inner side of the pipe to remove any sharp burrs that might damage the outer coating of the wire as it is pulled through the conduit.
• Once cut, the conduit is threaded into the end of the cut, allowing the user to make whatever lengths they need.

 EMT

• Lightweight metal
• EMT is commonly used for wiring branch circuits in homes (where electrical wires are exposed) and in commercial buildings.
• EMT is the standard for home installations.

EMT applications

• Especially for residential wiring.
• High quality ducts come in various lengths and finishes.

Don’t forget the fixtures

• IMC conduit comes in a variety of sizes to meet your conduit needs.
• Remember to include the accessories you may need to complete the project.

Electrical metal conduit (EMT), sometimes called thin wall, is commonly used in place of galvanized rigid conduit (GRC), because it is less expensive and lighter in weight than GRC.

EMT itself is not threaded, but can be used with the threaded fittings to which it is screwed.

Lengths of conduit are connected to each other and to equipment with clamp-type fittings.

EMT is more common in commercial and industrial buildings than in residential applications.

An EMT is generally made of plated steel, although it may be aluminum.

Features and specifications

• Precision manufactured to provide economical protection and long term value for your wiring system and electrical substations.
• Manufactured from high quality hardened steel that combines electrical and mechanical performance with ductility.
•  Impact resistant and easy to cut, bend and splice for smooth, continuous raceways.
• Strong, lighter and less expensive.
• Lightweight ductile steel channel for long life and easy to bend
• Hot galvanized outer and inner surface to increase corrosion resistance and rust protection
• The inner coating creates a smooth, continuous path for fast wire drawing
• Protect computers and other sensitive electronic equipment from the effects of electromagnetic interference.

coatings

• This process combines zinc, transfer coating, and a clear organic polymer top coat to form a triple layer of corrosion and corrosion protection.
• The inside of the barrel is coated with a highly corrosion-resistant lubricant for easy wire drawing.

With its hot galvanized threaded steel construction, this metal conduit provides a similar amount of strength as rigid conduit

• It is designed with a diameter suitable for fast wire drawing.
• Recommended for use in hazardous locations.
