When could using larger size conduits be beneficial?

Using larger size conduits can be particularly beneficial when bends are required in the installation process. When conduits must navigate around corners or curves, a larger diameter conduit helps to reduce friction and allows for easier installation of wires and cables. This is especially crucial when dealing with multiple wires, as a larger conduit can accommodate them without risking damage or excessive stress on the insulation. Additionally, larger conduits provide more space, which is advantageous for future upgrades or replacements, making the installation more versatile and accommodating changing electrical needs.

While straight runs might also benefit from larger conduits in some cases, the specific scenario of bends presents unique challenges that are more effectively managed with a larger size. Therefore, the context of bends emphasizes the primary advantage of using larger conduits in terms of ease of installation and maintenance.
