DEFINITION

Classification: 174/68.2

Bus bars or bus ducts (residual):

(under subclass 68.1) Subject matter pertaining to bus bars or bus ducts.

(1) Note. This is the residual subclass for subject matter directed to bus bars and bus ducts which is not provided for in any of the other bus bar subclasses of this class namely, subclasses 16.2, 70, 71, 72, 88, 99, 129, 133, and 149. Since, with the exception of subclass 16.2, the other bus bar subclasses in Class 174 do not have individually tailored definitions, determination of the subject matter falling within this subclass (68.2) can only be made after comparison with these other bus bar subclasses.

(2) Note. Examples of the subject matter found in this subclass are: bus bars supported on an insulator without an enclosing bus duct, bus ducts, per se, and certain bus bar and bus duct assemblies.
