I'm certainly no authority (or even an expert) on the matter, but if
you're talking about the fire happening at the plug/socket joining the
cord to the adapter, corrosion and loose fit seem like obvious
candidates.

I think that those sorts of interfaces are generally warm spots, since
the connection between two cords plugged together on the dock ay my
marina (for another boat moored too far from the power pedestals to
reach with a single cord) seem to have a lot less snow on them than the
rest of the cord. Also, my first winter aboard a neighbour two slips
down lost their boat in a fire that started at such an interface (it was
covered by a cushion in their cockpit).

To some extent, I'm tempted to blame your fire on "that's just what they
do; make sure you keep them clear of flammables".

Cheers,
Kris
