How long will these circuits last at these temps

Long enough for you to get the **** out of there.

Not enough information.

Just because something is 'hot' does not mean it's going to fail.

It may be a lot longer than you may think and 480 sparky may have a Valid point. I have been to Infared school & was the only Infared Specialist in the plant I worked in. We had many hotspots that were alot worse than yours, that we wouldn't address until an annual shutdown which might have been months later after my tests & reports. I would even find some of the same "hotspots" from the year before that were never taken care of. On the other hand one might get worse real quick & burn out or single Phase. On real big equiptment that draws many amps, we used to open the door and put a fan on it until we could get to it.................

Mike, did you bail on your Bulldogs before the season even began? Why the avatar change?

the 194F degrees is 90C degrees. Most wire ratings for high temp wire are in this range. But that looks like it was a fuse that was at that temp so eventually it will blow if it stays at those temps for too long, from repeated fatigue.

Would you not agree that heat is the major cause of all electrical and or mechanical failure it's not a matter of if but rather when is the failure going to happen

IRCharley

Sounds like a management decision not to repair until later or was that your recommendation based on temp recorded

mrmike

I think you have me confused with another mrmike on here. I have had this same avatar since I started...........

mrmike

Yes it was Management decisions & I would get Flustrated at times, But not too much of what I found would fail before then. If you think about it-there are loose connections in Homeowners panels for years without anything ever becoming of it. But it is that big one, as the Main connections, that can really cause problems. Usually it is the ones that draw high Amperage.
But an Infared camera is a very helpful tool for Preventive Maintenance & whatever is found to be "hot" should be adressed sooner than later !

Sure did.

Very true very helpful in my business I find a tremendous amount of 220 volt breakers for kitchen cook stove/cooktops with excessive temp due to loose connections and the high amps those suckers consume
