ABSTRACT:
An indicator particularly useful for indicating the increase in temperature for a bus bar joint, includes a first sheet-like member hingedly attached to a second sheet-like member. The first member is magnetically or adhesively attached to the bus duct cover. The second member is attached to the first member by a heat-sensitive adhesive. When the adhesive loses its adhesive properties upon reaching a predetermined temperature, the second member pivots down from the first member to provide an indication of an abnormal bus bar joint temperature.
