I was trolling youtube and came across this video. https://youtu.be/_Kl7OeTuvAY
At about 3:30 seconds in the video he talks about the temperature of the circuit breaks. He states if there is more than a 5 degree difference there may be an issue.
My questions is, since he doesn’t cite anything for this. Does anyone have any kind of reference for why you should check for a temperature difference or what is the basis for this?
Out of curiosity I’ve been checking the temperature as I go on service panels and came across one so I could post in here. Attached are pictures of a temperature difference.
It’s far beyond the SOP, but I’m curious to know. What does this mean and how could one know without knowing every type and manufacturer variances?
I found this old thread on this topic going back a ways also. http://www.nachi.org/forum/f19/checking-temperature-breakers-6154/
