This should be ideal for most applications, however if there are unwanted signals superimposed on the dc current it may be necessary to raise the trigger level above the 'noise floor' to get reliable results. If the trigger level is too high, no record will be generated on breaker operation.. “A Change is Gonna Come”. What Happened in the NEC 2014?. Big Changes, Big Headaches!.
