In the diagram of the switchboard shown in the illustration, what is the function of the device labeled "Gen. Bkr. Sw."? EL-0003

Correct Answer: Option D — it allows the alternator circuit breaker to be opened or closed remotely at the synchronizing panel

The generator breaker switch (Gen. Bkr. Sw.) on the switchboard synchronizing panel provides the operator with remote manual control to open or close the heavy-duty generator circuit breaker during paralleling and load-sharing operations, complying with IEEE 45 and 46 CFR Subchapter J control design requirements.
