Can you cut plastic conduit with a cable tray cutter?

Let’s delve into this question and explore the possibilities.

Understanding the Cable Tray Cutter

Before discussing whether a cable tray cutter can be used for plastic conduit, it is important to understand what this tool is and how it works. A cable tray cutter is specifically designed to cut through metal wires and cables, particularly those used in cable tray installations. It typically features a rugged cutting blade and a leverage handle to provide the necessary force for a clean and precise cut. The design of the cable tray cutter may vary depending on the specific model and manufacturer, but they generally share the same purpose.

Considerations for Cutting Plastic Conduit

Plastic conduit, on the other hand, requires a different approach when it comes to cutting. While a cable tray cutter may appear to be a suitable tool due to its cutting capability, there are certain factors to consider before attempting to use it for cutting plastic conduit.

1. Material Composition

Plastic conduit is typically made from PVC or another type of plastic material. These materials tend to have different properties than the metal wires found in cable trays. Plastic is softer and more flexible, making it less resistant to cutting forces. Therefore, the cutting mechanism of a cable tray cutter may not be ideal for plastic conduit, potentially resulting in a rough or imprecise cut.

2. Shape and Diameter

Plastic conduit comes in various shapes and diameters to accommodate different wire sizes and installation requirements. The cable tray cutter’s design may not be optimized for cutting these specific diameters or shapes, making it difficult to achieve clean and accurate cuts. A cable tray cutter’s cutting blade may not have the necessary curvature or edge to effectively cut through plastic conduit, potentially causing damage or distortion.

3. Safety Considerations

Using a tool for a purpose other than its intended use can compromise safety. While a cable tray cutter may be effective for its primary use, attempting to cut plastic conduit with it could lead to accidents or injuries. The inadequate cutting force or improper blade alignment may result in slips or unintended cuts, endangering both the user and nearby personnel.

Alternative Tools for Cutting Plastic Conduit

To ensure a precise and safe cut on plastic conduit, it is recommended to use tools specifically designed for this purpose. Here are some popular options:

1. Conduit Cutter: This handheld tool is specifically designed for cutting plastic conduit. It typically features a ratcheting mechanism, allowing for clean and precise cuts with minimal effort.
2. PVC Pipe Cutter: Similar to a conduit cutter, a PVC pipe cutter is designed to cut through PVC pipes and conduit. It uses a scissor-like cutting mechanism with sharp blades that create clean cuts without deforming the conduit.
3. Hacksaw: A hacksaw with a fine-toothed blade can also be used to cut plastic conduit. While it may require more effort, a hacksaw generally provides more control over the cutting process, ensuring smooth cuts without damaging the conduit.

While a cable tray cutter may excel at cutting metals, it is not recommended for cutting plastic conduit. The differences in material properties, shapes, and safety considerations make alternative tools such as conduit cutters, PVC pipe cutters, or hacksaws more suitable for this task. By using the right tool for the job, you can ensure precise, clean, and safe cuts on plastic conduit, meeting the needs of your electrical installations.
