Hammond Manufacturing 4-in Wide Copper Ground Bus Bar 2-pack

In Stock

This Hammond 4x10 inch Bus Bar has 0.25 inch tin plated copper rated 3200V glass-reinforced thermoset insulators.


  • 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
