CPC Definition - Subclass H02B

Last Updated Version: 2016.11
BOARDS, SUBSTATIONS, OR SWITCHING ARRANGEMENTS FOR THE SUPPLY OR DISTRIBUTION OF ELECTRIC POWER (basic electric elements, their assembly, including the mounting in enclosures or on bases, or the mounting of covers thereon, see the subclasses for such elements, e.g. transformers H01F, switches, fuses H01H, line connectors H01R; installation of lines, cables, or other conductors for supply or distribution H02G)
Definition statement

This place covers:

  • Electric enclosures such as electric boxes, circuit-breaker boxes, electric cabinets, low to high voltage switchgear enclosed in casings, cabinets or in switchyards, enclosed and non enclosed substations, for the supply and distribution of electric power.
  • The installation, maintenance and association of switching devices and switchgear with each other or with other electric devices, in such enclosures, substations, switchyards.
Relationships with other classification places

When the focus is on details of switching devices, like constructional details and not so much the association with other electric devices or enclosures, these devices are classified in H01H. The same applies to specific details of electrical connections, to be classified instead in H01R.

Cabinets that are referred to as electric(al) cabinets but are in fact enclosing electronic, telecommunication or data devices are not classified in H02B.
