•Electro tin plated copper bus bar, 100/300 micro inches of plating
•The thin tin coating acts as a shield, inhibiting copper oxidization
•Copper oxidization causes a poor electrical contact which then gets hot and increases the copper oxidization rate
•Oxides, because of their poor conductivity, also cause arcing at the electrical contacts, eroding the copper
