ADDITIONAL INFORMATION REQUEST 1.
Please provide schematic diagrams showing controls and indications related to motor-operated molded case breakers and electro-mechanical transfer switches.
2.
Label Figure 2 to show the normally open (NO) and normally closed (NC) alignment of the breakers in MCC's that supply the MUV's.
3.
To meet single failure criteria the motor-operated molded case breakers that are connected to separate ES HCC's should be physically separated. Verify that this will be the case.
4.
What is the earliest date by which this modification could be completed?
