Light fittings are exceedingly rarely a cause of electrocution.

Except when some health and safety ****t insists the fitting gets earthed.
Hold the fitting with the left hand and change the bulb with the
right....


And why the British system is superior to say, the Chinese system. My son
got a belt unscrewing an ES lamp from a fitting in China due to:

1) It being an ES fitting[1];

2) China, in common with a lot of countries has no enforcement of polarity
so in this case the cap happend to be live rather than the tip[2].

[1] Modern British ES fittings disengage on the first turn or so, the old
ones of course just had an all metal recepticle. However, even in Britain,
plenty of the older type exist.

[2] Even if the British regs demand the tip be live and the cap be neutral,
there's no guarantee some pillock hasn't wired it up wrong.

Which is why I hate ES fittings, and regard BC as generally a better idea.
