Nonmetallic auxiliary gutters must be supported at intervals not to exceed what distance?

Nonmetallic auxiliary gutters must be supported at intervals not to exceed 3 feet. This requirement helps ensure structural integrity and safety by preventing sagging or deformation of the gutter systems that could arise from unsupported spans. Proper support at regular intervals is crucial for maintaining the effective performance of these gutters, which are designed to handle the flow of water and prevent damage to the building structure. The specific span limit of 3 feet has been established based on industry standards and best practices to provide adequate support for the materials used in nonmetallic gutters, which may have different physical properties compared to metal gutters. Ensuring the proper support distance helps to comply with electrical codes and safety regulations in installations.
