This define how to test a circuit breaker through different simulations of its operation, which can be directly commanded from the circuit breaker analyzer, or initiated by an external signal, checking the opening or closing time of each pole, in single or combined operations (O, C, O-C, C-O, O-C-O, C-O-C), and checking the possible difference between poles or mismatch time which may lead to a dangerous lack of synchronism.
LOL... Test it with high current injector, not just by pushing the tripping button with your longnose pliers... your test cannot be accepted during commissioning test..
