Longest meter tails you've seen in a property?

[SSE]

The property I was at today meter tails need upgraded as the supply to the consumer unit ain't big enough, anyway the local authorities power supply comes in the garage to an old fashioned isolator (one of those with the handle on it) and then the meter tail comes out and travels about twenty meters to a brick wall, goes through it to an old fuse board at the other side. Never seen one go twenty metres before! Am sure theres bound to be someone here who has seen longer?!

Can someone please explain why the requirement for a switch fuse? I know the 'meter tails over 3m' bit but am trying to understand the reasoning behind it.

What I don't understand is what is different 'protection wise' between having a service head with a fuse, and having a switch fuse? apart from the switch bit of course ;-) or is the requirement to have a SH with a fuse, and a switch fuse?

Cheers

Someone, anyone?

The service head fuse is about as subtle as a brick.

For the reasons you don't need protection for <3m, courtesy of Richard Burns off another thread...have a look at these regs: This protection can only be omitted for a cable run less than 3m and protected to prevent damage.
