I have no further info on the unfused square pin plugs.
The consensus of opinion seems to be that they exist in countries that have different rules, possibly similar to our old 5Amp and 15 Amp round pin circuits, whereby our concerns relating to their use backed up by 30/32 Amp ring circuits are not their problem.
They are a problem to us if they sneak into the UK - so watch out for 'em and keep cutting those plugs off eh!
Regards
