Distribution Blocks Bus Bar

Distribution Blocks Bus Bar

Busbars are used to consolidate multiple wires or feed multiple circuits. Tin plated copper buses provide maximum conductivity and corrosion resistance. 

A bus bar is designed to make a solid connection point from one source to many branch circuits.  Or many branch circuits back to a single source.  More often than not a bus bar is used on the negative side of the circuit, because the switch panel is used as the positive source distribution method.
