SITC of floor mounting cubicle type indoor compartmentalized 415 Volt. 50 Hz. dust & moisture proof L.T. distribution panel (CPRI tested) board fabricated from 16 SWG CRCA sheet. The panel should have adequate strength and space to accommodate the incoming & outgoing switches and bus bars with all inter connections in between the switches & bus bars with solid copper rod / flexible wire of suitable capacity. The panel should be provided with cable alley for facilitating connection of all the incoming & outgoing XLPE cables with termination arrangements by supply & fixing copper terminal bar / bolt of required sizes.

The 2 nos. G.I earth bus bar should run along the full length of the panel board. The incoming terminals of ACB & MCCB as well as out going terminals of MCCB should be provided with Extra copper bar of suitable capacity for smooth termination of double feeders. All incoming / outgoing ACB / MCCB / SFU units should have identification as directed by the E.I.C. The panel board should be painted by powder coated paint & the layout diagram of the panel board should be approved by the E.I.C before manufacturing. The panel board should comprise with the followings :
