New-build AC that kept tripping the breaker

A new home in Irvine's Great Park whose AC kept tripping. The day before, the company that installed the system added a hard-start kit. It lowered the start-up current, but the breaker tripped again ten minutes after they left. With a thermal camera we found the fault was the breaker itself: one point in the panel was running over 100°F while the AC drew a normal 12 amps. We replaced it and re-terminated the wiring. After ten minutes of running, that spot read about 91°F, the same as the rest of the panel.
