Hm, 1 MPa.

Probably a bit more - it's 1mm dia wire, not 1mm², still 1N is equivalent to only around about 102g (4oz).

I fear the moment to worry about the finer points of the product standard was lost along with the box of original glands that should have come with the enclosure. The best anyone can sensibly do now is make it a little harder for kids to drop paperclips and coins in, and to keep out any water. At least its not in a damp basement with a coal dust and earth floor and a half inch puddle beneath it

Either I have an odd profile of friends with especially  dicky accommodation, or there are a reasonably high fraction of truly horrible installations in the basements of smaller block of flats made from converting Victorian townhouses  and things, that every one agrees are wrong and even dangerous, and at the same time no-one really dares touch as the responsibility is unclear.

But I reckon a decent snotting of mastic or grip fill is better than nothing and may well hold off a 1N force... just make sure it does not bear your fingerprints in case there is any comeback.

I wonder if  it's one of these Lucy units - https://www.lucyelectric.com/product/10-way-msdb-horizontal-busbar/

   - Andy.

if it is one of those, then the inside looks  like this. The silver bits are tinned copper, not steel ;-)

For what they cost the N-E bus routing for customer tails is not all that straightforward. Photo shows it set for TNC but the link between the two brass bars at the top can be removed to make it TNS, and then that almost encourages the exit tails not to be sensibly paired, as there is one fuse under each hole, but all the neutrals are in the bar on one side and all the CPCs in the other.

Often wondered why one phase gets an extra outbound fuse, but hey ho.

Note the rubber deformable strip at the to provide sealing of outbound cables.

It could be worse - it could be half a dozen sets of henley blocks hanging in the breeze.

In my opinion that is a job for the DSO/DNO to fix.  That white box at the bottum of the picture holds their fuses hopefully in a tamper proof enclosure.

As an observation the cables around the meters and iso's could do with some fire rated fixings or all round band

OK, round not square = 1.27 MPa.

Often wondered why one phase gets an extra outbound fuse but hey ho.

I wondered that too - most such units seem to have a number of ways that are a multiple of 3. Maybe the thought is 9 flats + 1 landlord's supply for a few corridor/stair lights and the occasional vacuum cleaner - so negligible extra load.

The internal fuse units look rather similar to one we usually see stand-alone or in the top of a cut-out (https://www.wt-henley.com/pdf/14688_series_7_house_service_cut_outs_2.pdf) in which case there might be reasonable protection from access to live parts if the sheath of the tails is taken into the terminal recess - as is the case with normal cutouts with upward facing terminals. (Well, if we adopt the DNO fashion of not regarding N as a live part.)

With this in mind who owns the red link “fuse” before a local meter?

if the red link  is part of a building network, then the DNO responsibility usually ends at their fuses, which  are the earlier ones, so the building network operator - which in reality may mean whichever contractors have been called up by the hassled sounding agent of the property management company, and be a different company each time. It could be you.....

But in older buildings the old electricity 'boards' would have been responsible, but in most cases this has changed and you can find that the person responsible does not realise they are, and no maintenance since the year dot
