Copper To Aluminum Bus Bar Connections

Silver plated multipurpose 110 copper bars with rounded edges.

Copper to aluminum bus bar connections. So when correcting for weight aluminum is far more conductive than copper. Bus bar connections often fail because those making the connections fail to follow the basic rules. As a result the once common plated copper bus bar is no longer what you re likely to encounter. A brief introduction to the advantages and disadvantages of copper busbar and aluminum wire.

Because aluminum has this imperfect surface and is also subject to thermal expansion and contraction which is 42 higher than copper there is a greater risk that. An aluminum bus bar must be thicker than its copper counterpart to achieve the same amount of conductivity.

Aluminum offers many possibilities including laminated bus and insulated bus bar connectors. 3 copper busbar is lower resistivity. 1 copper busbar is large load than aluminum busbar. Aluminum and copper bus bar also improves the reliability of a power or electrical grounding connection by eliminating the need for a mechanical cable lug crimp.

2 copper busbar is more flexible than aluminum wire. The superior ampacity of electrical bus bars help achieve better thermal control in enclosed applications.
