Definition statement

This place covers:

  • Installation of flat, laminated or tubular non-insulated busbars, mostly for high current/voltage applications.
  • Medium to very high voltage, gas-insulated tubular busbars arranged in a metallic casing.
Relationships with other classification places
  • 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.
  • When the subject matter is a supporting insulator for very heavy busbars and not the busbar itself, it should be classified in H01B 17/18 and not in H02G 5/025.
  • The subject matter might be double classified in H02B 1/20 or H02B 1/21 when related to the installation in electric cabinets.
  • Details involving the busbar casing and means for detecting mechanical or electrical defects are normally also classified in H02B 13/045 and H02B 13/065.
