Carefully dismantling 2 nos. of existing cubical LT panels from their installed positions. Take proper precautions to avoid damage to reusable parts and surrounding structures. Disconnect and remove all associated power and control cables, including cable sockets, glands etc. Ensure safe termination of insulation of exposed cable ends as per safety standards. Dispose all non-reusable or damaged components as per applicable norms. Installation of 1 No. Cubical Panel: Reinstall 1 no. cubical panel at the designated location as per the layout and instruction of the Engineer-in-Charge (EIC) by Wall Grouting and Fixing: Perform necessary civil work, such as drilling, grouting, and wall anchoring to mount the panel securely. Use appropriate anchor bolts, frames, and grouting compounds for sturdy and vibration-free installation. Reinstall all Switch Fuse Units (SFUs). Ensure proper alignment and mechanical fixing inside the panel compartments. Carry out internal wiring within the panel as per the approved schematic. Connect incoming and outgoing power cables, control wires, and earthing connections as directed. Use proper size cables, lugs, glandings, and insulating sleeves per standards. Perform continuity, insulation, and phase sequence checks. Ensure tightness of all terminations and phase identification tagging. Carry out testing of functionality of the panel and devices post-installation.
