Double Busbar Panels :
DOUBLE BUS Switchgear Panels with Automatic Bus Transfer Schemes are regularly supplied by us. Their utility is the provision of another set of busbars to supply power when one source fails or the flexibility to share the load on the Grid and / or a separate source. Each busbar is connected through Isolators or Circuit Breakers which are mechanically interlocked so that either one of them operates at one time. Enough protective equipment is provided so that power transfer between the busbars takes place smoothly and safely.
