Abstract
An electrical circuit for use in an electrical junction box of a vehicle, has two bus bars welded to each other at a weld. A first one of the bus bars is formed of a material having an electrical conductivity selected from (a) in the range of from about 10 to about 60% and (b) not less than about 60%, and the second of the two bus bars is formed of a material having an electrical conductivity of not less than about 60%. At least one of the bus bars is tin-plated and at the weld the bus bars are joined through a tin-plating layer. Appropriate selection of the bus bar material in view of current loads is achieved, and good welding results.
