What color circuit breaker triggers an ECAM 'CB Tripped' message when it has been tripped for one minute?

• A. Green
• B. Red
• C. Yellow
• D. Blue

Answer: (A)

The concept tested is how ECAM detects and reports a persistent circuit-breaker trip. When a breaker opens and stays open for about one minute, ECAM raises a “CB Tripped” warning to alert you to a sustained fault rather than a momentary blip. The breaker shown on the ECAM is color-coded to identify the affected circuit; in this scenario the color used to identify the tripped circuit is green. That’s why green is the correct answer. Other colors are used for different groupings or statuses of breakers and do not correspond to this specific persistent-trip alert.
