4 Tips to Select the Best Flexible Metal Conduits Solution

When it comes to choosing the right flexible metal conduit (FMC) solution, it can be overwhelming because of the variety of options available. Flexible metal conduits are commonly used in electrical installations, providing protection for wiring in environments that may be exposed to hazards. To help you make the best choice, here are four essential tips for selecting the best flexible metal conduits solution.

1. Understand the Different Types of Flexible Metal Conduits

Flexible metal conduits come in several types, each suited for specific applications. The two most common types are:

• EMT (Electrical Metallic Tubing): Lightweight and easy to install, EMT is primarily used in dry, indoor applications.
• Flexible Metal Conduit (FMC): More versatile than EMT, FMC can bend and flex, making it ideal for tight spaces and moving parts.

According to a report by Research and Markets, the global flexible conduits market is projected to grow at a CAGR of 5.8% from 2020 to 2025, driven by demand in various sectors, including construction and oil and gas.

2. Assess the Environmental Conditions

The environmental conditions where the conduit will be installed are crucial in determining the right FMC solution. Consider factors such as:

• Moisture levels
• Temperature fluctuations
• Exposure to chemicals or hazardous materials

For instance, flexible conduits used in outdoor applications must be rated for UV exposure and moisture. According to the National Electrical Code (NEC), specifications state that conduits in harsh environments must meet stringent safety standards, which can vary depending on the type of application.

3. Consider the Size and Type of Conductor

Your electrical system's requirements will significantly influence the size of the conduit needed. Flexibility and size go hand-in-hand, as larger conduits are generally stiffer. The following points are essential:

• Ensure the conduit size accommodates the conductor without causing damage.
• Avoid overfilling the conduit, as it can lead to heat buildup and potential failure.

The American National Standards Institute (ANSI) suggests that the conduit fill should not exceed 40% of the interior area of the conduit to ensure proper heat dissipation.

4. Evaluate Code Compliance and Standards

Ensuring that your chosen FMC solution complies with local codes and standards is crucial for the safety and legality of your installation. The following standards are particularly important:

• National Electrical Code (NEC)
• Underwriters Laboratories (UL) certifications

In a study published by the International Electrotechnical Commission (IEC), installations that followed applicable codes and standards noted a 30% reduction in electrical hazards, highlighting the importance of adherence to regulations.

Conclusion

Selecting the best flexible metal conduit solution can significantly impact the efficiency and safety of your electrical installations. By understanding the types, assessing environmental conditions, considering conductor size, and ensuring compliance with codes, you will be well on your way to making an informed decision. Remember to always consult industry professionals when in doubt to ensure that your choices meet all necessary requirements.
