Seems like a lot of wiring and separate little boxes to handle not so many
circuits.

I presume that it provides service for more than just one little hotel room.

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.

<shrug> it's in a cupboard, out of sight.

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

Heh.

But you're the tit that thought we put them on open view in our living
rooms.

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...

No idea what 'flip flopping' you're boring on about, but if you're
unable to understand my posts, I suggest you take some classes in
remedial English.

here to my house here in Grosse Pointe

Is this it?

<http://upload.wikimedia.ORG/wikipedia/commons/a/a1/GrossePointeMansion.jpg>

From the style of many of the houses in Grosse Pointe, one might
think one was back in a very salubrious part of England.

It doesn't belong in a closet for a rented room!

Sure doesn't, but remember much of the UK housing stock is old and
predates electricity. My house still has the lead pipes embedded in the
walls which were used to feed gas lighting, and much of the old lead-
sheathed power cables (copper cores wrapped in waxed paper then sheated
in a lead outer). No longer in use, thankfully.

We did not have the "cleansing" effects of a world war fought in our
country to push us along.

On the contrary, the cost of the war meant that little money was
available to improve the existing housing stock and little new was
built. What was built were cheap prefab houses intended to be
temporary. Indeed, some of those survive and are now "listed", which
means they are protected from inappropriate modification and/or
demolition.

It's not binding on the rest of the world but the town I lived in in Germany
looked like it had been reworked from top to bottom *after* WW2. We had
416 3 phase in our apartment for heating water.

Germany has done very well since the war - a lot of money was ploughed
into the country to rebuild. Some would say too much. American and
European money.

Yes, the salutary effects of higher voltages on conductor size are very
apparent. U.S. standards for wiring are getting to be excessively expensive
to implement.

the rocketing price of copper certainly doesn't help.

Aluminum was tried and rejected for general house wiring

no wonder when you see photos like these:

http://inspectapedia.com/aluminum/wirefire.htm

I think, but am not sure, that it was briefly tried in the UK but not
many installations were carried out before it was withdrawn.

Some older phone infrastructural wiring in aluminium is still in use
(mainly in trunk cables) and those are known to severely degrade ADSL
sync speeds.

You have to remember that when most of our standards were developed and
widely implemented, copper was a cheap byproduct of mining silver. ;-)

Boy, have tomes changed ;-)

Type "1600 prestwick grosse" into Google Maps and you can see my house from
several angles. Step a bit east of the default location for the best
possible view looking about north.

So many cables on those poles. What on earth are they all?

That really isn't pretty.

We did not have the "cleansing" effects of a world war fought in our
country to push us along. Also, electrical distribution had a very rapid
and early introduction so we have a ton of very old work that is still
in use.

AFAIK the nearest three phase distribution point here to my house here
in Grosse Pointe is about a half mile away. Our church here in town has
a number of 3 phase motors and it has its own 3 phase line and separate
pole transformer for just that phase.

I've never quite understood why so many US towns seem to have overhead
wiring for mains. It's very unsightly.

 

[Mike Tomlinson]

You might be surprised to hear that in the Detroit metro area Aldi (under
the eponymous and Trade Joe brands) is probably the number 2 retailer of
groceries.

Not surprised, no. Aldi and their very similar competitor Lidl have
many stores in the UK. I think some of the food is of better quality
and cheaper than the established British supermarket chains (Tesco,
Sainsburys, Asda, Morrisons). Meat particularly is good.

The pole transformers aren't pretty either, though produce quite
spectacular pyrotechnics when they fail, which seems to happen more
often than it should.

I use Lidl for some things. Not fresh vegetables, though. Or meat. Dairy
products are good value as are most other non fresh things.
Their tools in general are excellent - far better than budget stuff
elsewhere. But are only ever on special offer so you need to look out for
them. Don't have an Aldi anywhere close.

Pole transformers here seem to be a resource of last resort, usually
in a rural backwater. They have multiple taps on them so the linesman
can do his best to recover as much of the 240 volts as he can, despite
their distance from the nearest substation.

SWMBO shops there a lot, including for meat, fruit and veg. Good quality
at good prices. We regularly shop at Lidl in the Netherlands too, where
the wine is especially good value.

If everything is on a ring, why are there an odd number of breakers?

The ring returns to the same breaker. There isn't a separate one for
each end of the ring.

[John Williamson]

The breakers are 4 pole?

No, the breakers are normally only single pole, breaking the live only
with the neutral and earth (ground) being permanently connected to a bus
bar. Both ends of the ring come to the same point on the breaker.

There's a diagram and explanation of how these circuits work here:-

[Don Pearce]

The breakers are 4 pole?

No, you poke both wires into the same terminal hole.
