How to Cut Flexible Metal Conduit

The spiral construction of flexible metal conduit (FMC) allows it to coil between walls and other buildings. Electrical wiring in commercial and industrial buildings is protected by FMC. The LFMC (liquidtight flexible metal conduit) is a form of FMC with a plastic covering.

Conduits are flexible or stiff tubes that serve as a shield for electric wires. They are built of various materials and can be flexible or rigid. Flexible conduit is preferred over rigid conduit by many individuals because it is easier to fit in narrow and angled places. This flexible conduit is available in a variety of materials, including plastic, metal, and others A flexible conduit is utilized in places where a stiff conduit isn’t possible. Because the duties for which a conduit is employed differ, each conduit must be designed for each purpose. It is not difficult to learn how to cut flexible conduit. Cutting flexible conduit is simple and requires only a few tools that you most likely already have on hand. As always, work carefully, work safely, and have fun with your project. By picking the appropriate metal cutting tool for the operation, you will guarantee that it is as safe as possible. With a little effort and advice, anyone can perfect it. I’ve covered everything there is to know about cutting flexible metal.

How to Cut Flexible Metal Conduit?

Electric circuitry is shielded and routed via electrical conduits. Steel, plastic, fiber, and discharged clay are just a few of the materials that may be used to make them. Channels are available that are both adaptable and inflexible. Wiring regulations defined by national and provincial codes identify the type of avenue utilized. When working with Flexible Metal Conduit, there are a few options for shrinking it to the appropriate size. Although an adjustable conduit is considerably simpler to work with than a rigid one, it provides less protection for the conductors it transports. It’s difficult to bend an inflexible channel, therefore it’s usually easier to go with the adaptable option. Steel conduits offer an advantage over PVC conduits because they are more durable.Comply with these steps to cut an adaptable metal conduit effectively for the safest setup.

Tip 1 – Measure Distance.

Measure the distance between the two sites where the conduit will be run with a tape measure. Take into account the conduit’s bends. Remember to leave enough room at either end to secure it in the box.

Tip 2 – Place Channel in Vice.

If your vice has a port, make sure your cut mark on the avenue is aligned with the slot. If your vice doesn’t have a port, you can use a regular vice to get the job done. The cut mark should be off the end of the channel. You may easily suffice without any avenue activity if you do it this way.

Tip 3 – Cut the Conduit.

A fine blade hacksaw can be used to cut the conduit. This is the preferable method, despite the fact that it appears to be standard. Throughout, the straightness of the reduction was maintained. Although it may appear that you have a straight and also reduced, raveling the cut prior to use is a good idea.

Alternatively, you might use a different approach using a specific reduction gadget. However, the majority of them puncture the subsequent complete convolution by leaving the end of the conduit at a sharp angle. This angle will very definitely have to be straightened out before the cut end of the conduit is joined to a package or an adaptor.

Tip 4 – Smooth Out the Edge.

Fix any faults on the cut end using a tiny file and diagonal pliers, including an angled edge. You may also need to use a hacksaw to remove any remaining little parts. For the most effective fitting, you’ll need the best possible edge, especially if it’ll be utilized as grounding.

Tip 5 – Tidy up.

Completely and safely clean up your work space.

So, we can say that the above tips should be maintained properly to cut a flexible metal conduit.

How to Cut Flexible Conduit?

The term “flexible” refers to the Liquid-tight Flexible Metallic Conduit (LFMC), which is used to offer the electric raceway solutions required in NEC Article 350. The LFMC’s product standards are covered by UL 360, whereas Conduit Fittings comply with UL 514B. The product features and test criteria for listed LFMC and conduit fittings are outlined in UL 360 and UL 514B together. Impact, crush resistance, ingress ratings, temperature, strength, bending, flexibility, flammability, and other performance parameters are evaluated using these standards.

Liquid-tight Flexible Metal Conduit is made out of a spiral core, which is usually galvanized steel. Brass, aluminum, and stainless steel are examples of other conduit core materials, each with its own set of qualities for specialized applications. The spiral coiled core enables for flexibility while also protecting the conductors and wires it will transport mechanically. The conduit’s adaptability in static and dynamic applications is influenced by the core design, materials, and trade sizes. The jackets are usually made of PVC, although they can also be made of thermoplastic rubber, polyurethane, or PA nylons.

Flexible Conduit Systems are commonly utilized in installations where connections must be made with flexibility and the system may be subjected to stress and vibration. The following factors should be considered while choosing a product:

The application’s and industry’s particular needs

System ingress ratings.
System temperature ratings .
Approvals/certifications.
Indoor or outdoor installations.
Long-term performance consistency.

The Ways of Cutting Flexible Conduit are Given Below :

Step 1: Measurement Of The Project.

The first step is to figure out how many conduits you’ll need for your project. When measuring the turns on your project, make sure you measure each one independently. This will assist you in determining the distance over which the conduit will be run. The conduit size should be the same as the size of your project.

Step 2: Check The Size And Material.

Flexible conduit comes in a variety of sizes and materials, so you may verify the size of the conduit depending on the dimensions of your project to see whether it’s close to what you need. The sizes vary from 12 inches, 1 inch, 2 inches, 3 1/2 inches, and 6 inches. They also come in a variety of materials, allowing you to select the one that best matches your needs.

Step 3: Measurement Of Conduit.

Because a conduit is highly flexible, make sure you never cut it when it is extended when cutting it, otherwise it will wind up being too tiny when you try to fit it into your job. Make sure the conduit isn’t stretched, then use a tape to measure and mark the length of the conduit you wish to cut. It is recommended that you bend the conduit and cut it to produce a clean cut, and then relax when it returns to its original position. It will not be corrupted in any way.

Step 4: Using A Vise Or A Jig.

If you’re using a vice to hold an object in place while working with it, the next step is to place the conduit in the vise; this will allow you to easily cut the conduit without it moving. There are a variety of vises designed to cut flexible conduits, but if you don’t use it frequently, a standard bench vise or woodworking vice will suffice. Another device that holds the item of work and directs the tool is a jig. You may use a vise or a jig to do this.

If you’re going to cut your conduit using a hacksaw, you should utilize a vice or a jig. If not, you may skip this step.

Step 5: Cutting The Conduit.

There are different tools you can use to cut the conduit.

Hacksaw: When cutting through materials other than wood, a hacksaw is the best instrument to use. Hacksaw teeth are narrower and shorter than traditional saw teeth, making it ideal for cutting through pipe and conduit, and all blades are interchangeable.

Rougher edges will result from fewer teeth per inch, but you will be able to cut more quickly and forcefully. If you’re only cutting a few of pieces of conduit, a hacksaw will suffice. A bandsaw is the preferable alternative for a more professional cut and if your conduit requires additional cutting.

A bandsaw is quick and simple to operate, and it produces a beautiful, clean cut. To operate a bandsaw, start by turning it on, then bend and insert conduit slowly into the saw. You must rotate the conduit up and down at 90 degrees while the blade is cutting it. Here, the blade does the most of the work.

When using a hacksaw, be sure you utilize a sharp blade with a TPI of 24-32. This ensures precise and clean cuts. It’s critical to make sure you’re not damaging or disrupting the conductors while cutting the conduit.

Step 6: Smooth The Edges.

Because the edge of the conduit will be sharp no matter what tool you use after cutting, the next step is to smooth it out. A little file or diagonal pliers can be used for this.

If there are any remaining little edges that need to be cut, a hacksaw can be used.

Step 7: Clean Up.

Cleaning up the conduit’s edge is the last thing you’ll want to do. The conduit will be risky to work with and more difficult to install if it has a burred or sharp edge. With a few fast passes with a metal file, that edge may be removed, making the conduit easier to deal with.

Cutting flexible conduit is a skill that any DIYer or inexperienced electrician should learn. Cutting flexible conduit is very simple, and you can do it yourself with a few tools you presumably already have. Always remember to work intelligently, work safely, and have fun with your project!

Cut straight along the mark you drew for measurements on the pipe with your hacksaw. Sliced as carefully and evenly as possible until you’ve completely cut through the pipe.

Handsaw with Electric Motor:

A powered handsaw is likewise small and controllable for cutting stiff conduit, although it is heavier. You can use a motorized handsaw to cut a huge volume of conduit or many cuts. This flexible metal conduit cutter will help you minimize fatigue by keeping the blade and the conduit at a 90-degree angle.

Pipe Cutter:

Cutting conduit with a pipe cutter requires less work, but it requires more operation and the pipe must be held in an elevated vice. You should make sure that the blade is aligned with the cutting line and that it is tightened until it makes contact with the pipe.

Reamer:

If you wish to cut flexible metal conduit, you’ll need a reamer. The purpose of the reamer is to remove any burrs that have developed within the pipe. You may need to swipe the reamer within the conduit until the burrs are gone after using a cutting metal conduit pipe. After reaming, use an industrial-quality file to smooth off the edges. Before you begin cutting flexible metal conduit, keep an eye out for the following dangers.

Bandsaw:

This is optional, but if you’ll be cutting a lot of conduit, you might want to consider investing in a bandsaw. It’s time to make your cut now that you’ve completed all of your preliminary work and measurements. Cutting will be quick and easy if you are confident that you have measured and marked everything correctly. Here are some instructions for cutting the piece. This first set of instructions will show you how to use a bandsaw to cut wood.

Pick the right blade:

Make certain you use a metal bandsaw blade.

Power Up:

Boost your saw’s performance.

Bend Conduit:

Bend the conduit and pass it carefully through the saw. As you move, the blade will perform the work.

Rotate:

As you move the conduit up and down, rotate it roughly 90 degrees. Continue in this manner until the saw has completely cut through the conduit.Cutting metal conduit using a bandsaw is a safe and effective technique to do the task.

Vise/Jig:.

If you’re cutting conduit with a hacksaw, you’ll need a vise or jig to keep it stable as you cut. If you’re using a vice to hold an object in place while working with it, the next step is to place the conduit in the vise; this will allow you to easily cut the conduit without it moving. There are a variety of vises designed to cut flexible conduits, but if you don’t use it frequently, a standard bench vise or woodworking vice will suffice. Another device that holds the item of work and directs the tool is a jig. You may use a vise or a jig to do this.

Tip:

If you’re going to cut your conduit using a hacksaw, you should utilize a vice or a jig. If you don’t have any, skip to step 4 and cut your conduit.

Use a tape measure to acquire the exact measurements and lengths you require.

To be able to mark your cutting positions on the conduit, you’ll need a marker.

Shape or file :

any rough edges or components with a metal file.

Because you’ll be working with tools and exposed wires, you’ll need work gloves to keep your hands safe.
