Its not that hard.
Half of the inch part is 1/2 inch which is also 4/8.
half of the 3/4 part is 3/8 you get by multiplying the denominator by 2.
Put it all back together and you get the 4/8 part and the 3/8 part so in total its 7/8 of an inch.
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.
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.
