tighten again. (The clamped cable does relax over a short time).

Good grief. Considering the number of such terminals in the average
house carrying a great deal more current, I'm surprised there's not
fires everywhere. ;-)

The number of mains plugs I've removed that are very very loose is
amazing.

Not only mains plugs I've just selected two ring mains sockets at random and
one terminal was loose and the others could take a tightening.
the loose wire had not arced because the two conductors were twisted
together. Some sunny day I'll go around the lot.
How's your mains?.......is that a burger frying? Don't lose any sleep over
it ;-)

Twisting single strand mains cable is frowned on these days. With the
standard two cables into each ring main socket it isn't needed. For a
socket which is a spur, and therefore only one cable, I double over the
conductor.
