No no I understand. And I also understand why British Gas weren't happy installing with that behind it and personally I'm happy to upgrade it, also because DNO are going to change it to a PME.

i may be inaccurate here, but theoretically the protective device, usually a 1361, will blow long before the fault current gets anywhere near it's rated breaking capacity of 16kA. it's a very rare occurence for a fault current to develop upstream of the circuit protective devices, although not unknown.
