PCC panel

A Power Control Centre (PCC) panel is a low-tension (LT) switchgear assembly used to receive power from a source (mains, DG set, or transformer) and distribute it to various sub-feeders and motor loads in an industrial or commercial facility. It acts as the nerve Centre of power distribution and motor control.
