Explain why it's always the neutral terminal screw that comes loose in a

Is it ? Is this a 'well known fact' or something ? Are you actually
serious ?

Deadly. I check the mains plug on every bit of kit that comes across my
bench, and in at least 50% of cases, one terminal screw will be loose, and
that is *almost* invariably the neutral one. There has been discussion about
this in trade magazines, so amongst proper service engineers, it would seem
to be well known.

Adrian C's explanation sounds quite convincing.
