Copper To Aluminum Bus Bar Connections

3 copper busbar is lower resistivity.

Copper to aluminum bus bar connections.

A brief introduction to the advantages and disadvantages of copper busbar and aluminum wire. Aluminum offers many possibilities including laminated bus and insulated bus bar connectors. Just as often however the connections fail even when people do follow the basic rules. To learn more please contact storm s engineering team by calling 800 394 4804.

Also known as etp copper it s often used in electrical applications such as for bus bars and wire connectors as well as for flashing gaskets and rivets. As a result the once common plated copper bus bar is no longer what you re likely to encounter. 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. 1 copper busbar is large load than aluminum busbar.

So when correcting for weight aluminum is far more conductive than copper. 2 copper busbar is more flexible than aluminum wire. The superior ampacity of electrical bus bars help achieve better thermal control in enclosed applications. An aluminum bus bar must be thicker than its copper counterpart to achieve the same amount of conductivity.

Why in the early 70s the epa came down hard on plating facilities. 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.
