What is the maximum spacing for supports of 10 AWG copper conductors in a vertical raceway?

The maximum spacing for supports of 10 AWG copper conductors in a vertical raceway is determined by the National Electrical Code (NEC) requirements. Specifically, the NEC stipulates that conductors must be securely supported at specific intervals to prevent sagging or damage, ensuring safety and efficiency in electrical installations.

In the case of 10 AWG copper conductors, the maximum spacing for vertical supports is set at 100 feet. This means that every 100 feet, there should be a support to hold the conductors in place properly. This precaution helps maintain the integrity of the wiring system, prevents mechanical stress on the conductors, and ensures compliance with safety standards.

By adhering to this guideline, electricians can ensure not only the safety of the installation but also the reliability of the electrical system over time.
