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.
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.
The standard length of rigid metal conduit (RMC) is typically 10 feet. When including one coupling, the effective length might be slightly less depending on the type and design of the coupling used. However, for practical purposes in installation, the 10-foot length is commonly utilized. Always check local codes and manufacturer specifications for any variations.

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.
One problem of using rigid conduit in a residency when it is not needed is that project will very quickly over run the budget of the project. Labour will be at least 5 times more expensive to install rigid over NMD90 cable.Another problem will be the tight bends required in home wiring as compared to the radius bends that rigid conduit requires.
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.
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.
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.
For a 400 amp service, you would typically use a minimum of 3-inch rigid metal conduit (RMC) to accommodate the large conductors required for that amperage. It's essential to consult local electrical codes and regulations to ensure compliance with sizing requirements for your specific installation.
Adequate spacing for supporting rigid metal conduit typically ranges from 10 to 15 feet in normal conditions. However, this distance may vary based on specific factors such as conduit size, weight, and location. It is important to consult local building codes and regulations for precise spacing requirements.
4 inch rigid conduit
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.
A rigid conduit fill chart provides information on the maximum number and size of wires that can be safely installed in a specific size of rigid conduit. It helps electricians determine the appropriate conduit size for a given number and size of wires to ensure compliance with electrical codes and safety standards.
