Panel Hot

The service wire on top in this picture registered at about 150 degrees F. Is this normal when the AC is on on a hot day or dangerous? If dangerous, what could be causing the problem?

Nope, You have a problem. How did you read the temp IR Camera or Thermometer?

IR thermometer.

I see some melted insulation? Either way 150 degrees is not normal for only 30 to 50amps of load.

It may be significantly hotter than the reading you got with your thermometer.

Loose lug, hence high resistance and all that heating.
Defer! :wink:
