Overview
A main LT panel, also called a power control centre (PCC), is the heart of a building's or plant's electrical system. It receives power from the transformer or diesel generator and distributes it through outgoing feeders to sub-distribution panels, motor control centres and large loads.
We build main LT panels and PCCs to your single-line diagram and BOQ, from compact 600 A boards to power control centres rated up to 6000 A. Each panel is fabricated, powder coated, assembled and routine-tested in our Ghaziabad factory before dispatch.
