NIT NO. 17 ITEM NO. 20

Dismantling of old/existing panel from site after disconnecting the incoming and outgoing electric supply and shifting the material to store.

Fabrication of starter panel sheet steel enclosure made out of 2 mm CRCA sheet totally enclosed, powder coated free standing, floor mounted type, dust& vermin proof, outward opening, lockable doors having hidden hinges and a bolted back cover both using non-deteriorating neoprene rubber gaskets to provide IP-54 protection .The each part of the fabricated panel will be strictly subjected to seven tank treatment. The various components, assemblies and sub equipments of the panel will be as per standard given in relevant IS. The bus bar of the panel will be shaped out of high conductivity, electrolytic conductor and shall be liberal sized in aluminum. The control wiring of the panel will be done with PVC flexible copper wires of 1.5mm cross section. Each wire will be terminating with a ferule crimped to the wire, size 1700 mm x1000 mm x 350 mm. Having following components of approved make.
