Duct apparatus for distribution of isolated power and equipotential ground

A surface duct for distributing isolated power conductors and equipotential ground, comprising:

• a main body portion being essentially U-shaped, of extruded aluminum, having a pair of ridges running along the length of the open ends of said body portion, essentially perpendicular to the sides thereof, a mounting boss in the interior of said main body portion and extending substantially along the length thereof, said boss adapted for fastening a bus-bar to the top surface thereof, and a plurality of retainer protrusions in the interior of said main body portion located to retain at least one flexible partition;
• a bus bar mounted on said bus bar mounting boss.

A surface duct for distributing power conductors, comprising:

• a main body portion being essentially U-shaped, having a pair of ridges running along the length of the open ends of said body portion, essentially perpendicular to the sides thereof, an essentially T-shaped bus-bar mounting boss in the interior of said main body portion, a plurality of retainer protrusions in the interior of said main body portion located to retain at least one flexible partition therein;
• a bus bar fastened to the top portion of the "T" of said mounting boss by screws, and
• a cover plate removably attachable to the open side of said main body portion.
