Well somewhere in my system are some little gadgets RS used to sell as surge
protectors.They are supposed to put a shor on the line if the mains rises to
a certain peak. As yet one has never blown any circuit breakers. Now that
could be because its totally useless, I have no way to know!

Does anyone have any recommedations for Surge Protection Devices which are
suitable for use where they can't be fitted in a modern consumer unit?

How useful are SPDs where all the local wiring is under ground, but some
of the 11KV upstream of the local transformer is overhead?

I was surprised to discover that they are fitted in parallel with a
consumer rather before and in series.
