Default David or Charley

First one is the wires leaving the 60 amp breaker and going to the heat strips.

Second is the top heat strip. 5 KW

Loose connections? Should they be that hot?

Is that first one a parallel circuit? Two wires feeding the same equipment? (3 phase, 2 wires per leg feeding the same heaters)

If so, the hot one is not your problem. You have a bad connection on the cool conductor.

2nd pic looks like a thermal overload?
Need amperage on both of these.

Sorry for the dark pics it was in a corner of the garage. Here is a clear one for ya!

and yes since I went beyond and removed the cover, I found the great use of jumpers for interconnecting service breakers.
It was a 1989 Janitrol BTW... It seemed to work just fine..

I would say #1 is a bad crimp on the spade connector.

#2 is at the overloads. The center bank is not on (yet), or bad.
The top one comes on first. The others are on a timed sequence so they will show up at different temps at initial start up.

The rust will also look hotter than clean components.

That hot nut is connected directly to the heater coil. I would expect it to get very hot.

From the looks of it, the middle bank has never been used. It may not be hooked up. That is a lot of heat banks for TN if it is a heat pump.

Now don't get your G-string in a bunch just asking a question.

What jumper were you talking about the one from the incoming power to the second set of breakers. I sure wish ya would buy a amp meter

Ok I am done with the jokes what I see on your Jan-A-junk. is loose connections those spade clips have a tendency over time with a little heat to just expand out like a ripe banana or like Dave stated a bad crimp. Does appear the the middle strip was not operating but can not tell 100% with out a amp reading. Did I mention amp reading. Ya were a bit out of focus on your images but not enough to create those kinds of temps.

Ya can't call that double tapping on a service connect to a elec furnace that is how they feed all of the strips from a single power source

Charley & Dave's Rule of IR: If you don't do anything else, focus the camera and take an amp reading on any and all electrical scans.

Otherwise we will fling a dart at the dart board and give you a wild *** guess...

Oh BTW just wanted to say if ya keep doing the things you are doing above and beyond what is required you will become a sought after HI just from word of mouth. That was a good find in that strip heat most would never have found it just taking temps at the register. Keep up the good work

When he gets know as an undesirable in Knoxville for finding too much stuff that is actually wrong, let me know and I'll come work with him and we can just work the important jobs.

Writing a $1,300 report from yesterday and getting set for a $2,600 "home inspection" tomorrow... (don't get to many "Home Inspections" these days I'm too busy doing all the crap that we are not supposed to do...)

If the Feds don't quit messing with my retirement, I'll have to spread out and work longer...
