Here in Sweden I believe the most common is this kind of box: http://www.elbutik.se/group.htm?category_id=4826 It may be hidden in concrete or inside a wooden ceiling construction.
Together with this kind of cover, with electrical plug, with or without mechanical support. http://www.elbutik.se/group.htm?category_id=2532 The boxes are connected together with plastic tubing flexible or rigid. http://www.elbutik.se/group.htm?category_id=1919 /Janne Fran: [email protected] [mailto:[email protected]]For Matthias Weingart Skickat: den 25 maj 2004 14:25 Till: [email protected] Amne: Re: European wiring question On Tue, May 25, 2004 at 10:08:37AM +0100, John Allen wrote: > Thanks for the info - but I am probably not the only one who is a > little confused as to which of the boxes shown are used in CEILINGS to > support light fittings. > > Can you point out those used for this purpose? I am not a electrical craftman, but what I usually see is, that the pure cables are hanging down from the ceiling. Often there is no hidden box. The clamps were hidden in the case of the lamp or a small box arround the cable. Often the ceilings are made from concrete. It is impossible to hide a box there (but the simple drilling for the cable is no problem). However it is possible to use in-wall-boxes as like here: http://www.elektrofachmarkt-online.de/unterputzmaterial.htm The first ones are used in brick walls (but this is no longer officially accepted here), the latter orange ones in walls made of gypsum. Often the ceiling is taken down and you have a taken down ceiling made of gypsum or a construction made from wood. The lamps are integrated in the ceiling and the cables are between the taken down ceiling and the original ceiling. (I hope you understand :-). If this link does not work look for "Decken" "Gipsplattendecken" http://www.knauf.de/html/produkte/menue.php?lang=0&lid=1|19|24|25# I think you should ask your question in the usenet newsgroup news:de.sci.ing.elektrotechnik (you can post in english). I am not a specialist. M.
