Types Of Metal Conduit
Metal conduit protects electrical wiring in many buildings. It keeps wires safe from damage and fire.
There are different types of metal conduit. Each type fits certain needs and installation styles.
Rigid Metal Conduit
Rigid metal conduit, or RMC, is a thick and strong metal tube. It is usually made from steel or aluminum.
This conduit is very good for outdoor use and places where wires need extra protection.
Intermediate Metal Conduit
Intermediate metal conduit, or IMC, is lighter than RMC but still strong. It is often made from galvanized steel.
- Weighs less than RMC
- Used indoors and outdoors
- Resists rust and corrosion
- Easier to cut and bend than RMC
Flexible Metal Conduit
Flexible metal conduit, or FMC, is made from spiraled metal strips. It bends easily to fit around corners.
| Feature | Description |
| Flexibility | Can bend without tools |
| Use | Good for tight spaces |
| Material | Steel or aluminum strips |
| Protection | Less strong than RMC or IMC |

Cutting Techniques
Cutting metal conduit is an important skill for electrical work. It helps you fit conduit to the right length. There are several ways to cut conduit safely and cleanly.
This guide explains three common cutting techniques. You will learn how to use a hacksaw, a tube cutter, and power tools. Each method suits different needs and tools.
Using A Hacksaw
A hacksaw is a simple tool for cutting metal conduit. It works well for small jobs or tight spaces. You can control the cut easily with a hacksaw.
To cut with a hacksaw, first mark the cut line clearly. Hold the conduit steady with a clamp or vise. Saw slowly and evenly to avoid bending the metal.
- Use a fine-toothed blade made for metal.
- Keep the blade straight and apply light pressure.
- Wear gloves and eye protection for safety.
- Clean the cut edges with a file after cutting.
Using A Tube Cutter
A tube cutter is a tool designed to cut metal conduit quickly. It makes smooth and straight cuts. This tool is best for round conduit like EMT.
Place the tube cutter around the conduit at the mark. Tighten the cutter and rotate it around the conduit. Tighten more after each turn until the conduit cuts through.
- Ensure the cutting wheel is sharp and clean.
- Rotate the cutter slowly for a smooth cut.
- Do not over-tighten to avoid crushing the conduit.
- Remove burrs with a reamer or file after cutting.
Using Power Tools
Power tools cut metal conduit faster than hand tools. Common power tools include an angle grinder, a reciprocating saw, or a chop saw. Use the right blade for metal cutting.
Secure the conduit firmly before cutting. Wear eye protection and gloves. Cut slowly to keep control and avoid rough edges. Finish the cut edge with a file or sandpaper.
- Use metal cutting blades or discs.
- Keep hands away from the blade at all times.
- Cut in a well-ventilated area to avoid dust.
- Check the tool’s speed and power before use.
Smoothing And Finishing Edges
Cutting metal conduit leaves rough and sharp edges. These edges can be dangerous and may cause injury.
Smoothing and finishing edges makes the conduit safe to handle and improves its fit in installations.
Deburring Methods
Deburring removes sharp bits and roughness from cut metal edges. It helps prevent cuts and snags.
Tools for deburring include special deburring tools, rotary files, or sanders. Each tool suits different needs.
- Use a deburring tool to scrape off sharp edges
- Rotary tools can smooth edges quickly
- Sanders provide a fine finish for delicate work
Using A File Or Sandpaper
A metal file or sandpaper works well to smooth rough conduit edges. They are easy to use and widely available.
Files remove burrs by scraping metal away. Sandpaper smooths edges by abrasion. Both give better safety and fit.
- Hold the conduit steady while filing or sanding
- File in one direction to avoid uneven edges
- Use fine-grit sandpaper for a smooth finish
- Wear gloves to protect your hands
