Latest update. I cut back the burned neutrals, cleaned the grounds and every breaker now has power and nothing is overheating after 3 hours or so. THe only remaining thing is that the A/C (air contitioning) unit will turn on, run for a few minutes, then shut off, but not restart. If I recycle the breaker,fool with the thermostat, it will again start briefly ad shut off. So the original problem and subject of my original message is win and a fix, thanks to all those who tok the time to share their thoughts. And it was really quite easy. Who knew that replacing the buss and cutting back the neutral wires would work so well.
