This was in a panel where you could not see the sides of the connector. The Infrared Camera shows this to be approaching 500°. This was a case where the problem was fixed immediatly at whatever the cost. In this case it was minimal as we just shut down the Heat Trace for a few minutes and replaced the connections.

 

If left uncorrected, this was very close to melting down and causing several hundred dollars in collateral damage besides the lines to a very expensive componant of the plant freezing up and shutting the plant down.
