Which of the following describes why a larger conduit size may be necessary for cable installations?

A larger conduit size is often necessary for cable installations primarily to accommodate more bends without derating the cables. When cables are installed in conduits, there are specific bend radius requirements that must be adhered to in order to prevent damage to the cables and to allow for proper performance. If the conduit is too small, the cables may need to be bent more sharply, which can lead to increased attenuation and potential failures.

Using a larger conduit provides the necessary space to run cables in a way that maintains the required bend radius, ensuring that the integrity of the cables is preserved and their performance remains optimal throughout their lifespan. This consideration is critical during the planning and installation stages to ensure compliance with industry standards and best practices.

While heat dissipation is important, especially in larger cable bundles, it is not the primary reason for using larger conduit sizes. Different cable types can often fit into the same conduit regardless of size, and aesthetic requirements are more about visual appeal rather than technical necessity. Thus, accommodating bends efficiently is the crucial factor in determining conduit size for a successful installation.
