You don't want to be replacing them though if the protective device didn't disconnect fast enough under fault conditions rendering the tails thermally damaged.tails are usually visible though
...... Any cable needs protected by a suitable fuse and 100A is not suitable for a 6mm cable. I find it difficult to believe some are defending this poor practice. Its fundamental stuff.
The cable is fused by a 100A 1361 service fuse for gods sake. Read through section 712.............. The 6mm should have a 40A fuse in the DB at least or 25mm2 tails from "Henleys". The logic that suggests the service fuse protects the cable in the street would mean that at the end of each circuit should be a fuse. The 100A fuse protects the incomer from overloads and the ntails too. Any cable needs protected by a suitable fuse and 100A is not suitable for a 6mm cable. I find it difficult to believe some are defending this poor practice. Its fundamental stuff. How can a 100A fuse disconnect in enough time to stop a 6mm from bursting in to flames and setting the DB and tails alight too. I didnt come on here for a fight and had hoped for a better quality view. Its a shoddy job no matter what way you look at it and my client should not have been left in this situation. Neither should I have been put in the position of having to inform said client that the expensive job they have paid for is of doubtful technical quality.
As I understand it the 6mm cable is connected directly to the suppliers cut off, with only a 100amp suppliers fuse on the supply side to protect it in the event of a short circuit on that cable. The 16mm tails are irrelevant as they're feeding an unrelated 2nd distro board.
No way is this a safe installation, nor is it regs compliant as any cable needs to be protected by a suitably rated over current protection device, and this isn't from the info given unless I'm missing something.
