Re reduced-size earth conductor in UK cables -- Sorry, I goofed. [Linked Image] Shouldn't post when I'm tired after a hard day, and it seems to have been all go the last three or four days.

You'll see multiple neutral conductors under one screw terminal all the time here. Where the neutral bar has only as many terminals as there are circuit breaker positions, it's unavoidable with the use of ring circuits.

As we've discussed in other threads, I think too big a deal is made of polarized plugs for most portable appliances in Britain. Looking around the electric tools and test equipment surrounding me at the moment, I can see very little where polarity is of any consequence at all.
