CPC Definition - Subclass H02B
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.
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.
Attention is drawn to the following places, which may be of interest for search:
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, switches, fuses or line connectors | |
Installation of electric cables or lines, or of combined optical and electric cables or lines, or other conductors for supply or distribution |
This place covers:
- Electromechanical aspects of enclosures (boxes, wall mounted casings, electric cabinets) housing electric equipment mostly in the low and medium voltage range and the mounting of electric equipment therein.
- Details of electric equipment insofar as it is related to its mounting in the enclosure (mounting parts).
