Can a malfunctioning alternator blow the main fuse?

This happened on a Gen 5 Accord, but the issue applies everywhere.

Changing the alternator on a Gen 5 Accord I noticed that the inspection cover of the 80Amp battery fuse had partially melted. The fuse is still intact, but obviously had come close to vaporising at some stage.

Has anyone seen this before, or blown a main fuse as part of an alternator issue?
 
I guess if the regulator has failed then there will be some serious amperage going through the fuse and carrier enough to get it very hot,
Check the alt. output and see what its producing at idle and at 2000 rpm
