396. Diesel-generators #1 and #2 are operating in parallel with each machine operating at half-capacity. Diesel-generator #1 suddenly trips out mechanically due to low lube oil pressure. The reverse power relay functions properly and trips generator #1 electrically off the board. In the absence of an automated power management system, which of the following actions should you carry out FIRST?
Immediately reducing the load on the remaining generator is critical to prevent overload and potential blackout; therefore, stripping the board of nonvital circuits is the priority action.
