Outdoor Feeder Panel : Robust and Reliable

During my internship at Abhi Controls & Coatings i got a chance to work on Industry level project (Outdoor Feeder Panel). This distribution panel is designed to handle a 125A incoming load and distribute it efficiently to 12 outgoing circuits, each rated at 32A. It is engineered to meet the IPX4 series protection standards, ensuring durability and safety in various environments.

Busbar Design and Current Capacity

Main Incomer Busbar

The main incomer busbar is constructed using a 25mm x 10mm aluminum bar, capable of handling the full 125A incoming load. This configuration ensures:

• High Current-Carrying Capacity
• Minimal Heat Buildup
• Robust Performance

Outgoing Busbar

The outgoing busbars distribute power to the 12 individual 32A circuits and are made from 20mm x 10mm aluminum bars, providing:

• Safe Current Density
• Efficient Distribution
• Durability:
