Question # Industry Questions

1 LVA cannot provide breaker settings below 80A. So please let me know how you want to proceed with this issue having (10) breakers on the lineup.

Do you know the amperage breakers needed for the panelboard D1A/bus 1 & 2 ? LVA only provided single phase panelboard within the switchgear.

3 Will you be close coupling transformer to U1a (52A)?

4 Will you be close coupling transformer to U2A (52B)?

5 Does customer maybe plan to have SWGR as Main-Tie-Main and close couple to MCC?

Government Response

1. Breaker settings will be set by BOR.

2. Breaker ratings are shown on 485-D-60882. Panelboards shall be 3 phase.

3. U1A (MV switchgear) to be located on generator floor in same location as existing. U1A will not be close coupled to K1B or K1C because they are on different elevations.

4. U2A (MV switchgear) to be located on generator floor in same location as existing. U2A will not be close coupled to K1B or K1C because they are on different elevations.

5. D1A has will have a main-tie-main scheme. Equipment shall be close coupled similar to layout shown on 485-D- 60897.
