What does the term "bending radius" refer to in conduit installations?

The term "bending radius" specifically relates to the physical limits of bending conduit materials without risking damage. This minimum radius is crucial because bending a conduit beyond this specified limit can result in kinking or breaking, which compromises its structural integrity and functionality. Different types of conduit materials, such as PVC or metal, have different bending radius requirements based on their manufacturing properties.

The correct understanding of bending radius ensures that when installing conduits, electricians and contractors maintain the proper curvature, promoting safety and longevity in electrical installations. This aspect is critical particularly in installations where bends are inevitable, as maintaining the minimum bending radius helps to prevent issues related to wire stress or failures later on.
