Bus bar systems require jointing methods to connect individual bus bar sections or to make tap-off connections: 

• Bolted Joints: Bolted joints involve using bolts, nuts, and washers to secure bus bar sections together. This method allows for easy disassembly and reconfiguration.

• Welded Joints: Welded joints involve permanently joining bus bar sections through welding processes like spot welding or brazing. Welded joints offer high conductivity but can be challenging to modify.

• Compression Joints: Compression joints utilize mechanical connectors or clamps to join bus bar sections. This method provides a reliable and easily modifiable connection.
