DEFINITION

Classification: 174/34

(under subclass 33) Structures in which the conductors are associated together (1) in cable form or (2) in the same single or multi-duct conduit.

(1) Note. Conduit and cable structures combined with transposition boxes are in this class, subclass 33.

(2) Note. For multi-duct pipe or tubular conduit structures, per se, having the passages transposed, even though claimed as electrical conduits and even though claimed as made of dielectric, conductive or composite materials, search Class 138, Pipes and Tubular Conduits, subclasses 111+, and Class 285, Pipe Joints or Couplings, particularly subclasses 120.1+, especially subclass 132 for plural passage fittings with branches.

(3) Note. For conduit, cable, or conductor structures having twisted conductors without reference to any anti-inductive feature, see this class, subclass 68.1 and indented subclasses, particularly subclasses 102 and 110 and their indented subclasses.
