DEFINITION

Classification: 324/541

For insulation fault:

(under subclass 539) Subject matter for checking a defect in a nonconductive material which separate one conductor from another and causes an unintentional electrical path between two conductors.

SEE OR SEARCH THIS CLASS, SUBCLASS:

509+, where an insulation failure in a circuit causes an unintentional current leakage to ground.

544, for an insulation defect in a single conductor.

551+, for detecting the presence of a defect in a nonconductive material used in an electric circuit or component in general.

557+, for detecting defects in insulating material not used in an electric circuit or component.
