What is RMC conduit?

[whiteladybug342]

Rigid metal conduit (RMC) is a thick-walled threaded tubing, usually made of coated steel, stainless steel or aluminum. Electrical metallic tubing (EMT), sometimes called thin-wall, is commonly used instead of galvanized rigid conduit (GRC), as it is less costly and lighter than GRC.

Intermediate metal conduit (IMC) has a thinner wall than RMC and weighs about one-third less. IMC has a thinner wall than RMC and weighs about one-third less than RMC. The outside has a zinc-based coating, and the inside has an approved organic corrosion-resistant coating. IMC is interchangeable with galvanized RMC.

Additionally, what are the different types of conduit? There are seven different types of conduit used commonly in residential and light commercial wiring.

• Rigid Metal Conduit—RMC and IMC.
• Electrical Metallic Tubing—EMT.
• Electrical Non-Metallic Tubing—ENT.
• Flexible Metal Conduit—FMC and LFMC.
• Rigid PVC Conduit.

Moreover, what is RSC conduit?

Rigid Steel Conduit. Product Introduction: Electroline Rigid Steel Conduit (RSC) is zinc coated both inside and outside with hot dip galvanizing in such a way that metal-to-metal contact and galvanic protection against corrosion are provided.

What type of conduit should be used outdoors?

Nonmetallic conduit is typically made from PVC and is a good choice for outdoor residential applications. Blue electrical nonmetal tubing (ENT) is for indoor use only.
