GENERATION, CONVERSION, OR DISTRIBUTION OF ELECTRIC POWER

H 02 B

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 H 01 F, switches, fuses H 01 H, line connectors H 01 R; installation of electric cables or lines, or of combined optical and electric cables or lines, or other conductors for supply or distribution H 02 G)

Note

This subclass covers boards, switchyards, switchgear or their installation, or the association of switching devices with each other or with other devices, e.g. transformers, fuses, meters or distribution boards; such associations constitute substations or distribution points.
