They don't use boxes over there, you know
Loc: Stockholm, Sweden
I was googling the net for something and found an FAQ about international wiring. Never mind where, but the company has very good information and a range of international sockets, plugs and a whole lot of other things.
Reading the FAQ I noticed the following part:
Q: Why canâ€™t I find mounting boxes for European wall outlets, like those used in the U.S.?
A: The reason mounting boxes canâ€™t be located is Europeanâ€™s donâ€™t commonly use them. Because building practices and materials differ so greatly in Europe, and because the Building and Safety regulations are different, mounting boxes for electrical outlets have not been devised. Most, if not all, mounting boxes that are in existence were custom made for individual socket outlets by U.S. manufacturers who wished to have them. It may sound dangerous to us, that the Europeans donâ€™t use boxes to mount their wall outlets.
I contacted them and got a friendly reply, promising to look it up.

To this I responded the following. [Note: I leave out the pictures I included in the e-mail]
I believe there must have been a misunderstanding between you and your manufacturer.
Sockets like the single Schuko, 88010610, is the type you find mounted in
equipment. These need no box, as far as I know. Standardised boxes are only used
for in wall mounting. Your duplex Shucko socket 88010200 appears to be designed
for use in a standard 60 mm in-wall box.
The type of box used in many continental countries is a round box with screws on
60 mm centers. (The screws come with the box or separately, not with the
device.) The boxes can be ganged, in which case the distance between the center
of the boxes is 70 mm. Devices can be placed in single, double, triple etc.
frames. This way devices are in separate boxes, but share a common front.
See picture Boxes_60mm.jpg which shows the simplest boxes available here in
Sweden. The boxes are for different wall thickness and ganged for the catalog
photo only. The "tubes" are for holding rigid plastic conduit. In countries
using cables instead of conduit, boxes don't have these. For example see the
French mounting box in Simple_box_60mm.jpg.
See socket_outlet_in-wall.gif for a simple Schuko socket outlet intended for use
in a frame.
The picture frame.gif shows a typical double frame. You can put different
devices, like one socket and one switch in the frame. The frames are
manufacturer and model specific. (If the socket and the frame in the pictures
doesn't seem to match it's because the pictures are from different
Note that some countries, like Denmark, the UK and Italy have their own
standards. Also some countries might still stick to the old screwless box. In
this case, the device is fastened not by screws but by claws on the device. It
was probably the simplest solution when boxes were introduced in the 1930's, but
the shift to plastic boxes in the 1960's made it an obsolete design. See the
Switch_with_claws.jpg to see the claws. These fold out and grab hold of the box
when you tighten the screws. (And, it's a dimmer, not a switch.) Although most
switches and sockets have claws, all devices have screw holes too.
There is supposed to be a new IEC world standard box, but CENELEC has it on hold
until it has figured out what socket we are to use in Europe. Not this decade...
For surface mounted devices, the boxes used are manufacturer or series specific.
In some cases the box is even device specific. The design of these boxes depend
on the IP rating. For IP20 devices, simple frames with open backs are used. The
picture Socket_with_on-wall-box.gif shows this type of box with a timer and a
socket in a double frame.
To complicate matter somewhat, surface mounted devices are often designed as
self-contained units without need for a box. See picture
Socket_outlet_on-wall.gif . This is used "as is". Just make a cut in the gasket
at the bottom and pull the Romex style cable in. Rated for outdoor use, IP44.
Junction boxes, ceiling boxes and boxes for large devices appears to be
Do the ECN members agree with me?
