Description

The 1+1 Distribution Board (DB Panel) is a reliable and robust power distribution solution designed to provide continuous, safe, and efficient electrical power distribution for industrial, commercial, and infrastructure applications. The 1+1 configuration typically consists of two incomers—one main incomer and one standby incomer—with a changeover or bus-coupler arrangement, allowing the load to be transferred to the standby source when the main supply is unavailable or during maintenance.

• Key Features
• 1+1 incomer configuration for main and standby power sources.
• Main and standby incomers designed for reliable power availability.
• Manual or automatic changeover can be provided according to project requirements.
• High-quality ACBs/MCCBs/MCBs for reliable switching and circuit protection.
• High-conductivity copper busbar system for efficient power distribution.
• Properly arranged phase busbars and outgoing feeder connections.
• Individual protection for outgoing circuits to minimize the impact of electrical faults.
• Neatly routed and segregated internal wiring for improved safety and maintenance.
• Clearly identified cable termination points and terminal blocks.
• Phase identification using suitable color coding and labeling.
• Robust sheet-steel enclosure with a durable powder-coated finish.
• Lockable access doors for enhanced safety and controlled access.
• Adequate internal space for inspection, testing, cable termination, and maintenance.
• Provision for earthing and grounding of the enclosure and internal components.
• Modular construction allows future expansion and additional outgoing feeders.
• Components can be selected according to the required load, fault level, voltage, and protection scheme.

Operation:

Under normal conditions, the main incomer supplies the connected load. If the main source fails or requires maintenance, the standby incomer can be connected through the designated changeover or bus-coupler arrangement, ensuring continuity of power supply to critical loads. The changeover system can be configured for manual or automatic operation depending on the application.

Applications: The 1+1 DB Panel is suitable for:

Industrial plants and factories
Commercial buildings
Shopping malls and offices
Hospitals and healthcare facilities
Data centers
Infrastructure projects
Manufacturing facilities
Educational institutions
Power and utility installations
Critical electrical distribution systems
Customization

The panel can be manufactured according to specific project requirements, including rated current, voltage, number of outgoing feeders, incomer configuration, short-circuit withstand capacity, busbar rating, protection devices, metering, changeover system, enclosure size, and IP protection level.
