What is the minimum size for U-bolts on a Service Mast that is not over 26" high?

The minimum size for U-bolts on a service mast that is not over 26 inches high is 5/16 inch. This specification is critical because U-bolts must provide adequate support and stability for the service mast, ensuring that it can safely handle the loads and stresses it may encounter, including wind forces and the weight of the conductors. The 5/16 inch size strikes a balance between providing sufficient strength without being overly bulky or complicating the installation process.

If the U-bolts were smaller than this size, they might not provide the necessary support and could fail under stress, which could lead to safety issues. Conversely, using a larger size than required can lead to unnecessary costs and challenges during installation. Thus, adhering to the minimum size requirements specified in the relevant electrical codes ensures safety, reliability, and compliance with local regulations.
