Copper To Aluminum Bus Bar Connections

2 copper busbar is more flexible than aluminum wire.

Copper to aluminum bus bar connections.

Bus bar connections often fail because those making the connections fail to follow the basic rules. Why in the early 70s the epa came down hard on plating facilities. Silver plated multipurpose 110 copper bars with rounded edges. Aluminum offers many possibilities including laminated bus and insulated bus bar connectors.

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. 3 copper busbar is lower resistivity. An aluminum bus bar must be thicker than its copper counterpart to achieve the same amount of conductivity.

The superior ampacity of electrical bus bars help achieve better thermal control in enclosed applications. 1 copper busbar is large load than aluminum busbar. 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. 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.

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. Just as often however the connections fail even when people do follow the basic rules.
