Copper To Aluminum Bus Bar Connections

Nevertheless aluminum is significantly lighter than copper.

Copper to aluminum bus bar connections. 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. Why in the early 70s the epa came down hard on plating facilities. Just as often however the connections fail even when people do follow the basic rules.

Aluminum offers many possibilities including laminated bus and insulated bus bar connectors. 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. 2 copper busbar is more flexible than aluminum wire.

Bus bar connections often fail because those making the connections fail to follow the basic rules. To learn more please contact storm s engineering team by calling 800 394 4804. The superior ampacity of electrical bus bars help achieve better thermal control in enclosed applications. 3 copper busbar is lower resistivity.

So when correcting for weight aluminum is far more conductive than copper. 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.
