What is IMC and EMT?
EMT. IMC is typically compared to RMC, but in terms of weight, it lies between RMC and EMT, or electrical metallic tubing (also known as conduit). EMT is commonly used for branch circuit wiring in homes (where the wiring runs are exposed) and in commercial buildings.
How do you transition from rigid to EMT?
Quote from the video:
Quote from Youtube video: The way this product works is you simply insert your half-inch EMT. Until it hits the stop in the middle. You then tighten it onto the EMT conduit by securing it with a lock nut and turning the gland.
How often do you strap EMT?
EMT must be secured at least every 10 ft. and within 3 ft. of every outlet box, junction box, device box, cabinet, conduit body, or other termination. An exception allows EMT to be fastened up to 5 ft.
Can IMC be used underground?
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.
What does IMC mean in conduit?
Intermediate Metal Conduit
Intermediate Metal Conduit (IMC) provides a lighter weight, lower-cost solution for jobs that require the same strength as galvanized rigid steel conduit.
What is IMC conduit used for?
Intermediate Metal Conduit (IMC) is galvanized steel raceway. Used to protect and route conductors and cables, this IMC conduit can also be used as an equipment grounding conductor when installed with fittings and couplings in accordance with the NEC.
Can you mix rigid and EMT?
The combination coupling or the transition fitting is available for most of the applications in the field. The conversion of EMT to Rigid, EMT to FMC, Rigid to Liquidtight or any combination thereof can be accomplished using UL listed products.
What is an EMT pipe?
Steel conduit and electrical metallic tubing (EMT) refers to the steel-based durable enclosures that route individual electrical wiring conductors in a building or structure and protect the wires from impact, moisture, and chemical vapors.
Can you bend IMC?
Rigid and IMC conduit are the hardest raceways to bend because they have a much thicker and harder wall. ½” and ¾” rigid or IMC can be bent by hand using a hickey (or segment bender).
What is IMC tube?
Intermediate metal conduit, or IMC, is a rigid steel electrical conduit designed for outdoor exposure and strong connections. It was designed specifically to protect insulated electrical conductors and cables. It does the work of a similar metal conduit, rigid metal conduit (RMC), but weighs about a third less.
How deep does IMC conduit need to be buried?
. 6″
IMC (INTERMEDIATE METAL CONDUIT)
Intermediate Metal Conduit when installed underground shall have a burial depth of min. 6″. NEC 300-5. IMC may be used in hazardous locations.
Can EMT be used outside?
Electrical metallic tubing (EMT): Lightweight and easy to install. Intermediate metallic conduit (IMC): Has a thicker, galvanized wall, making it suitable for outdoor applications.
Can IMC be threaded?
IMC is just as easy to work with as GRC. Watch the video and learn how IMC is easily threaded and bended using the same process and equipment as rigid.
What is the minimum size of IMC?
Lighter and lower cost metal conduits.
| Trade Size | Average Outside Diameter | |
|---|---|---|
| (in) | (mm) | (in) |
| 2 | 53 | 2.36 |
| 2 1/2 | 63 | 2.857 |
| 3 | 78 | 3.476 |
Can IMC conduit be in concrete?
IMC can be installed in concrete, in direct contact with the earth, or in areas subject to severe corrosive influences where protected by corrosion protection and judged suitable for the condition. Just like rigid steel conduit.
What are the maximum number of bends allowed for IMC?
There shall not be more than the equivalent of four quarter bends (360 degrees total) between pull points, for example, conduit bodies and boxes.
What is the maximum trade size of IMC?
IMC Sizing
IMC is available in trade sizes 1/2 through 4, and 10′ lengths. Threads on the uncoupled end are covered by industry color-coded thread protectors to protect the threads, keep them clean and sharp, and aid in trade size recognition.
What is the maximum distance between supports for a straight run of 2 in IMC made up with threaded couplings?
(3) Exposed vertical risers from industrial machinery or fixed equipment shall be permitted to be supported at intervals not exceeding 6 m (20 ft) if the conduit is made up with threaded couplings, the conduit is supported and securely fastened at the top and bottom of the riser, and no other means of intermediate
Is IMC hot dipped galvanized?
IMC Conduit Galvanised Steel Tubing Rigid Hot dipped Galvanized Detailed Product Description Manufacturer Factory Direct IMC Conduit Fittings 1/2″ To 4″ Galvanised Steel Tubing Rigid Description: Hot-dipped Galvanized RMC/RSC Conduit with a integral coupling and a protection cap TOPELE… Length : 10 ft.
