BUS BAR ASSEMBLY

A bus bar assembly includes a first housing; a first bus bar extending through the first housing; a second bus bar extending through the first housing, the second bus bar including a second housing that defines at least one first receiver configured to engage a fastener; and a sensor assembly mounted to the receiver, the sensor assembly including a current sensor positioned between the first bus bar and the second bus bar. The sensor assembly may not include a magnetic core, and the current sensor may be a coreless sensor configured to detect a current through the bus bar assembly.
