'72 Tradewind - Hot Breakers

[reddog60]

The breakers get very hot (they do not trip), but the wiring is cool. The air will kick off when the breakers get hot, but comes right back on. Any idea what is causing this? Are new breakers needed?

Heat is usually caused by electrical resistance. If your breakers get significantly warmer than the ambient air (especially if they are very hot to the touch), it is usually an indication of high internal resistance; and it's time to replace them.

Yes, breakers fail that way. They are inexpensive, like around $5 each at Home Depot or Lowes. They are easy to replace.
