The wire has become HEATED, and the expansion/contraction of the wire can make it lose it's connection, or otherwise 'short circuit' the breaker, causing it to trip.

We had a loose neutral problem on the travel trailer we had before the ACE. We stopped at an RV park near the Little Big Horn Battlefield on a very hot day. We were running the AC and started smelling burning insulation and had smoke coming out of our breaker box. After opening it up, we found that the AC circuit neutral wire had burned insulation about an inch back from the connection and several other circuits showed some discoloration of the wires at the neutral bar. Tracked it down to a loose connection at the neutral bar on the AC circuit. Everybody got tightened.
As this was due to a poor neutral connection the breaker would not have seen any over current. We could well have had a fire if we weren't in the trailer to smell the impending fire and shut things off. So now all our AC connections at the breakers and neutral bar get a yearly tightness test.
