This will cause the breaker to trip or alarm (based on
WebDec 4, 2010 · A secondary injection test, on the other hand, is done by injecting a current with the contacts closed but with no current flowing on the poles. This is a better way of testing circuit breakers because it uses low voltage signals that are injected to the circuit breaker which prolongs the operating life.
