800A / Sq. inches.

4. Base frame of at-least 4" made out of steel sections is to be provided.

5. Panel will have :

Top Entry Bottom Entry

Floor Mounted Installation/Wall Mounted Installation

6. Bus bar system supports will be CPRI or equal test laboratory

approved.

7. All panel compartments shall have identification etched on Aluminum

strip.

8. All MCB DB will have each MCB identification

9. Stands should be provided for the installation of switch board

matching to height of the false floor.

10. All VFDs shall have an active-front-end design

11. All UPSs shall have an active-front-end design

12. KVAR Requirement for each transformer is 400 KVAR steps size

should be appropriate considering data centre application & to

maintain p.f .98 to unity.

Components :

1. MCCBs will be atleast 35 kA or as specified In SLD.

2. MCBs will be atleast 10 kA short circuit withstand of the curve to suit

discrimination

3. ALL protections will be coordinated

4. The range of the instruments be such that the readings will shown

the mid-range of the instrument.

5. The load manager will be installed with communication port and

win95 or similar graphic OS based software.

6. All ACBs will be draw out type with static relays provided for

over-curent, earth fault.

For DG set protection restricted earth fault protection is required.

7. MCCB to have following :

Shunt trip , fault indications, Electronics trip mechanism.

Earthing :

1. All doors will have flying earth.

2. Copper earth bus is to be installed.

3. Where applicable UPS system, VS system and Raw power earth shall

be separate. All the earth bus installed on suitable insulators

Drawings and Tests :

1. Shop drawings are required to be submitted for the review and

approval

2. Test certificates for all components and the panel's routine tests are

required to be provided in triplicate

3. Panel is required to be tested at site and works

8. All Panel Should Have Tvss Protection
