Copper for Busbars
If arcing occurs, copper busbars are less likely to support the arc than aluminium. Table 7 shows that copper can self-extinguish arcs across smaller separations, and at higher busbar currents.
Bus Spacings in Metal-Enclosed Switchgear
When considering bus spacings, two dimensions are important. The first is clearance, or the distance through air between conductors of opposite polarity or between an energized conductor and ground.
