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.
In galvanized steel, a thin coating of zinc is used to protect it from rust or corrosion.
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.
Simply put, no. The long answer: The process of chrome plating involves the chromium actually bonding to the metal substrate through an entergetic reaction. Galvanizing metal introduces a layer of zinc oxide into the mix which would contaminate the plating process. The chrome would actually split bond to the zinc and possibly somewhat to the substrate. This would cause the zinc to lose its bond with the metal substrate. If it all stayed intact the part would, at first, appear to be chrome plated, but due to the zinc oxide contamination it will flake off easily. I hope this is a sufficient answer to your query.
Galvanized iron is iron that has been coated with a layer of zinc to protect it from corrosion. This zinc coating increases the durability and longevity of the iron, making it resistant to rust and other forms of corrosion. Galvanized iron is commonly used in outdoor and industrial applications due to its corrosion-resistant properties.

intermediate galvanized conduit
intermediate galvanized conduit
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.

steel, but coated with zinc.
No, galvanized steel does not contain lead. It is coated with a layer of zinc to protect it from corrosion.
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.
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.
Industrial Electricians work in manufacturing plants, factories, power plants, ect. Rigid conduit is the usual raceway used, but also pvc coated rigid is common. also an industrial electrician will install and connect motors as well as motor control centers.

Galvanized means coated with zinc.
