Tails longer than 2m

[Monkeyblaine]

What is the main purpose of putting a SF inline with the main head for running mains further than 2m to location of CU?
I know it must be to do with the operation time of the DNO head but I can't figure out correct terminology.

if tails are > 3m, then it's recommended to fit a switch fuse with a lower In than the DNO fuse in order to protect the DNO fuse from a fault on the tails.

More often than not, it'll be a requirement of the local DNO!! Though some call for > 3m and others > 5m....
