Re: Electrical Wire Safety (Underground)

Speaking of England, what's up with the pull cord light switches in the
bathrooms?  In my experience, the pull cord was always a natural fiber,
never metal like you might find in the US.  Is there a significantly
greater risk of shock in a British bathroom, or is this simply done for
tradition's sake?

In England where I lived (the Potteries) all the utilities are (were)
under the sidewalks covered by large paving stones set in sand.  As is
obvious, expense and disruption was minimal.
