| Abstract: |
Disclosed is an electrical cable assembly in simplest form including at least one conductor, at least one insulator, and at least one attention getting material and/or a visual reacting material such as a thermochromic material or liquid crystal formulation, which will, visually and/or physically react to certain critical temperature ranges. May give off a response to variations in temperature an/or magnetic and/or electrical fields which are indicative of a hazard and/or fault, or to the direct and/or indirect results of electrical energy behavior, to provide an indication of an electrical overload condition, and/or a malfunction, and/or the incremental stages of hazard experienced by, and being experienced by, and to be experienced by, the electrical cable assembly itself, which undergoes on its own, at least one noticeable manifestation, to get your attention.

What is claimed is:
1. A hazard self-indicating electrical cable assembly comprising: at least one electrical conducting means; at least one electrical insulating means disposed around said electrical conducting means; and at least one attention getting means to indicate a malfunction in the cable assembly; wherein said at least one attention getting means includes a heat shrinkable material being coupled to said at least one insulating means, and is activable during the malfunction, said heat shrinkable material being adapted to shrink to a degree sufficient to deform the outermost surface of the at least one insulating means.
