Your sarcasm fails because actually I do know everything necessary to
check the safety of a mains extension lead. As do many people.

Unfortunately for technical pseudo-elitists it really isn't rocket
science.

Are you saying you've never come across such a thing miss wired, Bill? In
the days when people made up their own extension leads?

I've seen plugs where the brown went to earth. After all brown is closer
to the colour of earth than green.

If it's pre-harmonisation german equipment - red is earth

About 20 years ago one of our German research student wired a plug up, like that.
Perhaps that one reason why we don't allow DIY lead making and if we really need to they get PAT tested.
