Red fuse carriers

[sparkzalot]

Enclosed is a picture of a mains incoming supply to a block of flats as you probably already know. Now ignoring the odvoius faults (no blank plates) i am assuming that the red fuse carriers should infact be replaced with actual fuses??!! Out of shot is the landlords dis. board of which i was testing which had the tails straight into the board via the red cut out. Now assuming there are fuses in the suppliers grey enclosure surely they only protect each phase and not every single supply to the flats. Im gueesing this is incorrect can somebody please shed some light. Thanks

Likely that the fuses are located in the flats.

No they are red links, fuses are in the multi way.

i'd be more worried about the fact that the block of flats has fallen over.

So is this perfectly acceptable these days?? I was also under the assumption that anything 3metres plus from the cut out should also have a fused main switch (KMF) installed???

Hey t ... is it any wonder that you have > 40 k posts ... ;-P if they are like this one! I like it ...

probably just links, the fuse will be downstream local to the flats.

nothing wrong with downstream protection for fixed loads (the installation is from ryefield to cutout at flat)

Now sorted lol.

Are they definitely double pole switches in those metal clad isolators or are they single pole switched neural MCB's? Like this

The red links are just that, solid links used for isolation only. That is a multiway cutout, there will be a fuse for each supply in there.
You are right that tails are limited to a length of around 3metres, anything longer should have a distribution circuit. The DP units in those enclosures look wider than usual which suggests they may be 80A or 100A MCBs rather than just switches

The fuse will be in the cutout, that's a multiway jobby which is an alternative to fitting a ryefield type board which DNOs sometimes use, there's probably 9x 100A fuses in there.

Downstream protection has a few rules attached to it, one of them being a 3metre limit
