PROBLEM
A nonconforming internal circuit breaker component may affect the electrical protection capability of the circuit breaker. If the circuit breaker has the nonconforming internal component, it is possible that all poles on the circuit breaker may not open if the circuit breaker is called upon to interrupt current (trip), or if the circuit breaker is manually switched to the off position. If a circuit breaker pole/phase does not open, this may, in conjunction with other factors or circumstances, result in a risk of personal injury or death.
