Fixed vertical distribution bus bar

An electrical system comprising:

• a plurality of compartments, each compartment being configured to receive a unit having an electrical component;
• a plurality of vertical bus conductors, each vertical bus conductor having a plurality of substantially flat areas between substantially curved areas, the substantially flat areas each having an aperture providing a fastener exposed in a compartment;
• a plurality of horizontal bus conductors;
• and
• an electrically insulating bus support having a plurality of vertical channels configured to receive the vertical bus conductors, wherein the electrically insulating bus support electrically isolates the vertical bus conductors from the horizontal bus conductors,
• wherein each horizontal bus conductor is attached to a different vertical bus conductor,
• wherein the substantially curved areas are provided in a first plane and the substantially flat areas are provided in a second plane parallel to the first plane, and
• wherein the vertical bus conductors each further include a substantially flat area provided in a third plane parallel to the first and second planes, wherein the first plane is between the second and third planes.
