Support requirements for copper conductors in vertical conduit runs are indeed closer together compared to aluminum conductors. This difference arises primarily due to the physical properties of the metals. Copper is denser and has a higher tensile strength than aluminum, meaning that copper conductors typically require more frequent support to ensure they remain properly aligned and secured within the conduit.

The closer support points for copper conductors help in minimizing stress and potential fatigue in the wiring due to the weight and properties of the conductor. In contrast, aluminum conductors, being lighter and less rigid, can maintain their position with supports placed further apart.

Understanding these requirements is critical during the installation process to ensure compliance with electrical codes and to maintain the integrity of the electrical system. Proper spacing of support can prevent damage to conductors and ensure safe operation, making it essential for electricians to be aware of the specific support requirements for different conductor materials.
