Abstract

An electrical connector including a connector section and a connector performance indicating section. The connector section includes a first connection section adapted to connect to a first electrical conductor and a second connection section adapted to connect to a second electrical conductor. The connector section is adapted to electrical connect the first electrical conductor to the second electrical conductor. The connector performance indicating section is connected to a portion of the connector section. The connector performance indicating section includes a temperature sensitive indicator adapted to signal occurrence of a temperature of the portion of the connector section above a predetermined temperature. The temperature sensitive indicator comprises a Radio Frequency Identification (RFID) tag.
