Please do not take emphasis AWAY from the point that I was trying to make:

>We are required (by the standards, general morality, legal liability, etc)
to ensure that products will remain 'safe' under >worst case conditions.

>Hence we spend much soul-searching to evaluate and to test under
'worst-case' conditions.

The example was merely to show one area where designers get it wrong - and
there are too many to list - hence I emphasis the principle of
responsibility  - and worst-case...


In answer to your specific question: typically a manufacturer (wrongly)
selects a plug with a 13A marking and fits a 1,2,3,5,7Amp fuse. When the
fuse blows the user then replaces it with a 13A fuse. As per the generic
"13A" marking on the plug.

I have seen this done by many engineers in many companies - but it is only
ONE of the common errors.



Best regards

Gregg
