Overcrowding cables can lead to overheating, damage, or failure of the electrical system. Adequate space allows for heat dissipation and reduces the risk of damage from physical stress on the cables.
Measure the cable diameter, then choose a conduit size that offers a little extra room to ensure the cable can move freely within the conduit without being squeezed or constricted. Additionally, determine the length of the conduit required for the installation. Make sure the conduit is long enough to cover the entire length of the wiring run without unnecessary excess that could lead to waste.
Conduit Material and Durability
The material of the corrugated conduit plays a key role in its performance. Most corrugated conduits are made from either PVC, polyethylene, or other durable thermoplastics, each with its own set of characteristics:
PVC corrugated conduits are known for their chemical resistance, flexibility, and affordability, making them a popular choice for residential and commercial applications.
Polyethylene or other high-performance materials might be required for installations in environments exposed to high-impact conditions, UV radiation, or extreme temperatures. For outdoor or underground installations, polyethylene is often preferred for its durability and resistance to environmental elements.
Compliance with Standards and Codes
Ensure the corrugated conduit you choose meets the necessary local, national, or international standards and codes. For example, in the U.S., the National Electrical Code (NEC) provides guidelines for conduit usage, including material specifications, installation methods, and fire resistance ratings. Compliance with these standards ensures the safety, reliability, and long-term performance of the conduit system.
Budget Considerations
Finally, assess your budget for the project. While corrugated conduits are often more affordable than rigid metal alternatives, prices can vary based on the material, size, and specialized features like UV resistance or chemical resistance. For cost-sensitive projects, ensure that the chosen conduit offers the necessary features without exceeding budget constraints.
