  A lot of residences only have 100A service.  Older places might even
have 75A.  But even 75A is a lot (in household context).  Now, it's
possible for an arc -- like you get when wires short -- to perturb
protective devices upstream.  Might be that.  But yah, if the main
breaker popped on a branch overload, I'd want an electrician to check
the whole thing over.  Might be more than just a ceiling fan wrong.
