In electrical terms it represents Rigid Steel Conduit. It is also known as Rigid Metal Conduit (RMC).This is not to be confused with Electrical Metallic Tubing (EMT) also known in the trade as thin wall conduit.
depends on size....
It depends upon the construction of the building as to what type of electrical system is used. If the building is of a wood frame then ordinary home wiring system can be used. If the use of steel studs is involved then BX has to be used for the internal wiring. Where the cables come out of the walls to equipment, they have to be mechanically protected with conduit or flexible conduit. If the building is block or brick and the wiring system has to be installed on the surface, the system has to be conduit. If the installation is not engineered and no stipulation as to what type of conduit system has to be used, then go with EMT. EMT systems are labour and material wise cheaper than a threaded rigid system. To make the job look professional you need to hire someone that is good at bending EMT conduit. Ask to see other jobs that the contractor has done before letting out the contract.
2 inch Rigid or IMC conduit if it's on a structure. 2 inch schedule 80 PVC conduit if it's on a wood pole.
A trade size hole for a 2-1/2" EMT conduit connector, the hole needs to be 2-7/8" in diameter. A 3" rigid conduit can also use this size hole without the lock nuts falling into the hole.
There will be at lease three and on some conduits additional information. There will be the manufacture's name, type of material the conduit is manufactured from and the diameter size of the conduit. For example Scepter PVC 100 mm (for American customers 4") conduit.
rigid metal intermediate metal rigid nonmetallic
A 770 Greenlee hydraulic pipe bender bend is used for rigid steel conduit from 2" to 4".
Galvanized rigid conduit is coated with a layer of zinc to provide protection against corrosion. This coating helps to extend the lifespan of the conduit when used in outdoor or corrosive environments.
4 inch rigid conduit
There are two types of rigid conduit systems. One is PVC rigid conduit. It is mostly used in underground installations and in in areas that contain water or corrosive chemicals. The second type of rigid conduit is steel conduit. In Canada it is mostly phased out due to the high installation labour costs. Small installations are still used in small explosion proof areas.Both types of systems in Canada have been replaced with Tech armoured cable. Installation costs are lower and the wire is in the cable set, so no wires to pull. It is approved for above grade and underground direct burial installations. Tech also has been approved in explosion proof areas when used with the proper explosion proof end connectors to seal the cable.
Another name for thin wall conduit is EMT and stands for Electrical Metallic Tubing. The term thin wall is used to differentiate between two conduit systems, thin wall and rigid conduit systems.

Usually in the industry, we call it metal conduits. Metallic conduit is stronger, more durable, and more fire-resistant than non-metallic conduit. It is often used in industrial, commercial, and hazardous environments. Which included, Rigid Metal Conduit(RMC) Electrical Metallic Tubing (EMT) Intermediate Metal Conduit (IMC) Galvanized Rigid Conduit (GRC) Flexible Metal Conduit (FMC) Liquid-tight Flexible Metal Conduit (LFMC) Hope it works.
The metal which does not undergo any kind of deformation under the action of external forces on it is a rigid metal. It will not change in size, shape and position in response to external actions.
Another name for thin wall conduit is EMT (Electrical Metallic Tubing). It is a type of conduit made of steel that is commonly used for protecting and routing electrical wiring in commercial and industrial construction.
Require professional expertise and tools due to the difficulty in bending the conduit to fit. This can increase installation costs and complexity. Additionally, the rigid nature of the metal conduit makes it less versatile for installation in tight or complex spaces.
