In the September issue of Wiring Matters e-newsletter, one of the articles looks at the case of 'Colin', a recently qualified electrician carrying out a safe isolation procedure. Unfortunately for Colin, he makes an oversight which leads to him receiving an electric shock.
Read the article here and let us know what would have been your safe method of working for the job Colin had.
Its also not very clear how he got a bad shock - if all exposed cores are live how was the shock path completed - one foot in an external flower bed perhaps?
I have had one from a lamp fitting. Return path was screwdriver (not sheathed 
), me, synthetic footwear (not operating theatre ones, which deliberately conduct), wooden ladder, floorboards, joists, bricks, slate damp-proof course (could have been breached), more bricks and footings.
I wouldn't say that it was a "bad" shock, just a little nip really, but it made me feel foolish.
given how little the 's' in TN-s means these days
The diagram does not look like TN-s to me.
