Is IMC rigid conduit? A LIGHTER WIRING SOLUTION WITH STRONG PROTECTION IMC is manufactured as a cross between EMT and rigid metal conduit (RMC). A slightly thinner gauge than RMC, IMC is light but strong.
Is IMC rigid conduit?
A LIGHTER WIRING SOLUTION WITH STRONG PROTECTION IMC is manufactured as a cross between EMT and rigid metal conduit (RMC). A slightly thinner gauge than RMC, IMC is light but strong.
What is the difference between EMT and IMC conduit?
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.
What is the maximum percentage fill of conduit?
The NEC specifications are: One wire: maximum fill is 53% of the space inside a conduit. Two wires: maximum fill is 31% Three wires or more: maximum fill is 40% of the conduit’s total available space.
How much can you fill conduit?
Finding minimum available conduit area The National Electrical Code establishes that if a conduit only contains 1 wire, the max fill percentage is 53%. If it contains 2 wires, the max fill percentage is 31%. And if it contains 3 or more wires, the max fill percentage is 40%.
What is rigid conduit cut with?
Rigid pipe can be cut with such PVC pipe and tube cutters as hacksaws, power miter saws and scissor-type cutters, but ratchet-style cutters tend to strike an effective balance of affordability, flexibility and ease of use. With a hacksaw, slowly draw the blade back and forth, making sure that the cut is straight.
Is EMT the same as rigid conduit?
EMT is also called “thin-wall” conduit because it is thin and lightweight, especially compared to RMC. EMT is rigid but can be bent with a simple tool called a conduit bender.
What is rigid conduit used for?
Rigid Metal Conduit—RMC and IMC Rigid metal conduit, or RMC, is heavy-duty galvanized steel tubing that is installed with threaded fittings. It is typically used outdoors to provide protection from damage and can also provide structural support for electrical cables, panels, and other equipment.
Is rigid conduit stronger than EMT?
As you might expect, RMC is a lot more rugged than EMT. If you’re in an extremely cold climate, or in some other type of harsh environment, RMC will do a fantastic job of protecting wiring. RMC also does a great job of blocking electromagnetic interference.
How do you cut rigid conduit?
What’s the difference between IMC and rigid metal conduit?
Rigid Metal Conduit (RMC) and Intermediate Metal Conduit (IMC) are very similar in application. However, there are some distinct differences between the two. RMC is the thickest and heaviest type of steel conduit.
How big is a Conduit Fill in inches?

What’s the difference between RMC and IMC pipe?
Trade size Number 2, for example, has an inside diameter of just over two inches. Thread protectors are added to the uncoupled ends of both types of conduits to preserve the exposed threads and to identify the pipe sizes. RMC is manufactured in sizes ½ to 6, while IMC Is typically available in sizes ½ to 4.
When to use IMC in an Allied Tube?
The fact is that IMC is allowed to be used under “All atmospheric conditions and occupancies” according to Article 342 of the NEC. This same statement is made under Article 344 of the NEC in reference to GRC. A simple rule to remember for using IMC would be: If you can use rigid steel conduit, you can use IMC!
