The maximum support interval for 3/0 AWG aluminum conductors in a vertical raceway is indeed 180 feet. This requirement is based on the National Electrical Code (NEC), which provides guidelines for supporting conductors to prevent sagging, ensure safety, and maintain efficient operation. Vertical installations can experience different stresses than horizontal ones, such as those associated with gravity and weight distribution, which is why specific support intervals are established.

The NEC stipulates that conductors should be securely supported at regular intervals to mitigate potential hazards such as damage to the conductors or raceway, which could lead to failures or electrical shorts. Establishing a 180-foot interval helps accommodate the physical characteristics of the conductors while adhering to safety regulations.

Understanding this support requirement is crucial for ensuring compliance with electrical codes and maintaining a safe electrical installation. It's important for electricians and engineers to be familiar with such standards when planning and executing electrical work.
