The point where the equipment actually fails is somewhere above the design limit.

• A. Break point
• B. Design/ Test Limit
• C. Tech Spec Limit
• D. Trip Setpoint

Answer: (A)

The key idea is that the point where the equipment actually fails is the break point. The design limit is the maximum level the equipment is intended to withstand safely under design conditions. When failure occurs above that limit, it means the system has reached its ultimate failure threshold—the break point. Protective actions like a trip setpoint are placed to act before reaching that failure point, so they prevent failure rather than represent it. Tech Spec limits are regulatory operating bounds, and Design/Test limits are boundaries used for design and testing criteria, not the exact physical failure point.
