Relationship between large subject matter areas
  • When the focus is on details of the electrical connections between different parts and not so much the installation of the busbars, these documents should be classified instead in H01R 3/00.

  • The subject matter might be double classified in H02B 1/20 or H02B 1/21 when related to the installation in electric cabinets.
