Supply, installation, testing, and commissioning of an indoor-type LT Panel box, designed for IP-43 protection, rated at 415V, 1000A BBC, 50Hz.The panel construction will utilize 2mm thick CRCA steel/MS plate sheets reinforced on a 75X50X6mm angle iron frame, featuring front and rear openable hinged doors with door handle arrangements, including a locking arrangement.

The foundation for the panel will be constructed using cement concrete, ens-uring a robust and approved structure. This foundation will be sitespecific and will incorporate proper sizing of iron channels and angles to enhance stability and compliance with the EIC requirements. Additionally, the founda-tion, having a suitable size for the installation of the above-mentioned panel, is included in the scope of work. The panel will be securely mounted either in the floor or on the wall, as per the site requirements and in accordance with the EIC specifications. This mounting arrangement ensures optimal stability and accessibility for the efficient operation and maintenance of the LT Panel.

The LT Panel box will include interconnections between 415V Four Pole SFU. Heavy copper solid bars with necessary socketing will support the bus-bars, and FRP/DMC insulators will be used for insulation.Inside the panel, the interconnection between the main bus bar and all SFUs will be established using appropriate size copper bars and suitable spreader links. Wire connec-tions are not permissible for this purpose. To further enhance the reliabil-ity and efficiency of the panel, suitable size copper bars and spreader links will be provided for the outgoing terminals of all SFUs . This design feature aims to facilitate the connection of outgoing cable terminals, ensuring a robust and seamless electrical distribution system.Panel drawing detailling with busbar and interconnection cu strip arrangemant with cable entry and foundation details must be approved by EIC.

The panel dimensions will comply with the respective Bureau of Indian Standards (BIS) and site working space requirements. It will be painted powder coating with two coats of red oxide as a primer, followed by a final coat with synthetic light grey /Siemens grey shade as per IS 631.
