How do you wire a QO/QOB shunt trip breaker (ex. QO120-1021)?
Connect the appropriate voltage (ie. 120V to 240V for the -1021 suffix) to the two terminals on the shunt trip. Land the switchleg from the source contact on one terminal ( either) and the neutral wire (L2 , X2 ) to the other terminal . The shunt trip has coil clearing contacts that open when the voltage is applied so either momentary or maintained contacts can be used to initiate voltage .
