BUSBAR:-500V, 400 Amp capacity 99.9% – 99.5% electrolytic tinned 4 bar copper bus bar [size of flat 4x 50 mm x 5 mm] mounted on non-hygroscopic FRP/SMC/DMC insulator / hylam sheet having sufficient di-electric strength duly wrapped with colour PVC tapes (Red, yellow, blue & black) for phases & neutral identification - 1 set.

The busbar is to be rigidly supported on suitable non-hygroscopic insulating materials of robust ration to with stand electromechanical stress in the event of earth fault. All connection to bus to made by suitable nuts & bolts. The busbar is too wrapped with coloured PVC (Red. Yellow, Blue & Black) for colour identifications.

OUTGOINGS:-(i) 63A FP MCCB, 25 kA breaking capacity with thermal magnetic release protection. (Make- L&T / Legrand/Seimens /ABB or equivalent make as approved by EIC)- 16 Nos. (ii) Indicating LED lamps for On/Off/trip with protective SP MCB's. (Make- L&T/Legrand/Seimens/Rishabh Instrument or equivalent make as approved by EIC)- 16 Sets

Interconnection :-All interconnection between incoming main to Busbar are to be made with suitable size electrolytic tinned copper bars or equivalent flexible pvc insulated multistranded single core Cu cable as directed by E.I.C and the same between busbar to each outgoing mains and & for metering arrangements are to be made by suitable size of Copper with proper socketing of the end of each wire leads.

Earthing :-A separate continuous GI earth busbar of size 50mm x 6mm shall run across the full length of the panel board . All electrical equipment are to be properly earthed with suitable size G.I. wire.

The complete panel board is to be spray painted after required surface treatment by 9 tanks process / sand blasting with 2 coat of red oxide primer & 2 coat of finished paint over dried or powder coating with cable alley chember & ventilation facility.
