That would heat the wire, not the fuses themselves...

It would heat the connections, not the wire - and the connection at
the fuse holder could be heating even if it is physically tight

The heat will be generated at the high(er) resistance point(s) -- if
the wire were small-enough to be a voltage dropping element in the
circuit, it would be a distributed heater (albeit lower resistance
than, but similar to the dryer heating element). If the connections
are bad somewhere, they'll generate heat at that (those) resistance
point(s), not somewhere else.

If there were a stray path to ground it might be possible to draw
excess current over the normal load and still be under the fuse
ratings. But, any heating effects would still be effected at the point
(s) of higher resistance in the circuit. If only the fuse box/fuses
are overheating, there has to be a high resistance point there
somewhere--high resistance somewhere else can't transfer its I-squared-
R losses across the ether to be dissipated elsewhere.
