How do I read the seismic engineering details for cable bracing on heavy duct?
Use the approved seismic restraint package-not a rule of thumb. Match the duct run, size/weight, brace type, attachment, spacing, and allowable angle to the project-specific engineered detail.

If the run does not match the detail, stop and send the foreman the duct size, elevation, support layout, and conflict location for clarification.']
Use this as training guidance. The foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, and AHJ/code requirements always control the final answer.
Steps
Stop and verify the approved project detail, foreman direction, and manufacturer or engineered requirements before acting.
