I wouldn't worry too much, and I doubt that they will. From all you've
said I'd expect any overloads to be of fairly short duration (i.e.
minutes not hours) and not likely to do any great harm. (I'm assuming
here that you do have a 100 A main fuse, not a 60 or 80 A one.) Make
sure that nothing around the service position is getting excessively hot
- fishy smells are sure sign of problems.
