Yes, that's the main incoming supply to the building. The grey unit at the
bottom left is the supply company's terminating unit that inludes their
fuses. Above that is the meter, to the right of it is a neutral block, and
beyond that an isolator (looks like a three-phase + neutral one). I'm not
sure what the unit above the isolator is, but at the top of the wardrobe are
three consumer units, each, apparently, fed from a different phase. The one
on the right seems to feed just one, high-current, load.

While we're talking about electrical safety, what is the current (scuse

you have to use cable that is rated for 13A (1.5 mm^2 wire rather than 1

Indeed. It's a common error to assume that the reason that cable drums
should be unwound when in use is something to do with inductance. Possibly
because its a coil, and wire is commonly coiled up to create an inductor.
But in this case it is, as you say, simply a matter of air cooling, or more
to the point the lack of it. The inductance of an air-cored coil of
relatively few turns would be insignificant at 50Hz and in any case the
inductances of the two conductors largely cancel out.

shrug it's in a cupboard, out of sight. Mind you, whoever did that
obviously took pride in his work. Nice neat job (except the incoming
cable, maybe, it can't be touched anyway)

Where's the problem?

It's massive, ugly and looks like it came out of the Queen Mary rather
than a domestic premises. Apart from that, it's great :-)

Yes, it'll feed the entire building. Note the wiring includes the
supplier's meter, unlike those ugly external meters used in North
America. The meter is read remotely.

As another poster said, this is a 3-phase supply. Notice how thin the
main incomer is, yet that'll be supplying 100A per phase.

Ah, So *now* it doesn't matter how ugly it is.
Which was my point exactly.

Heh.

Now and again one has to apply the Ruler of Reason to the Knuckles of
Stupidity. I never said you did. I only stated that at *we* weren't stupid
enough to put them in our living rooms. If you thought I was implying that
*you* were, perhaps the shoe fits after all.

Heh.

Doh.

Anyway, I'm glad to see you've flip-flopped on the issue. Doesn't matter
what the **** it looks like if it's not out in the open living space.

I've seen US TV shows where they are in a public space in an apartment
block. Is this the norm?

I wouldn't go there. SWMBO'd town house in St Albans had the meter
and CU in the bin cupboard outside the front door. Simple through
door latch gave access to anybody. All the same type houses on the
estate were the same, I don't think any had even so much as a hasp
and padlock on the cupboard door...
