Is EMT conduit suitable for outdoor use?

Examples are electrical metallic tubing (EMT), which is lightweight and easy to install; intermediate metallic conduit (IMC), which has a thicker, galvanized wall, making it suitable for outdoor applications; and galvanized rigid conduit (GRC), which is thickest and offers the most protection.Click to see full answer. Considering this, can EMT conduit be used outdoors?It can be used indoors, outdoors, underground, and in both concealed and exposed applications. IMC has a thinner wall and weighs less than RMC. IMC can be used for the same applications as galvanized RMC. EMT is the lightest-weight steel conduit manufactured.Secondly, does outdoor wiring need to be in conduit? Generally, local codes require that outdoor wiring be protected by conduit in an instance in which outdoor wiring is installed above ground. If wiring will be buried, most codes allow Type UF cable. However, some require that Type TW wire and conduit be used. In respect to this, is EMT weatherproof? 2 Answers. I would not use EMT at all. It is not weatherproof. Those compression couplers (you know, the not-setscrew ones) are not for weatherproofing, they are for better grounds.Where can I use EMT conduit?Flexible metal conduit is great for areas that require tight bends and close quarters would make it difficult to bend regular conduit. Water heaters, can lights, and attic vents are great examples of typical flexible conduit installation. EMT conduit is lightweight, easy to bend, and is used within the walls.
