Matt Posted June 6, 2006 Share Posted June 6, 2006 I apologise in advance as I'm sure this has been coveredCan I use UK twin and earth in France and if so does it need to be in gain,conduit or nothing at all in the ceiling void. Link to comment Share on other sites More sharing options...
Matt Posted June 6, 2006 Author Share Posted June 6, 2006 Sorry ,just read the electrics glossary and that answered my uk t&e question.If I use the U1000 cable where do I need to put it in gaine and conduit.Matt Link to comment Share on other sites More sharing options...
Nick Trollope Posted June 7, 2006 Share Posted June 7, 2006 Are you referring to the coax cable spec? If so, then "the rules" mean that (assuming you are not using it for HV transmission!) you don't need gaine (or conduit) at all.Or are you referring to something else?

La Guerriere Posted June 7, 2006 Share Posted June 7, 2006 The French logic is that all cabling must be inspectable or pullable-outable. This seems to mean that you can use cable U1000 stuff anywhere, but if you bury it in walls or hide it in inaccessible voids it has to be threaded through gaine. Even if it just goes through a wall, there should be a bit of gaine through the transition Link to comment Share on other sites More sharing options...
P Posted June 7, 2006 Share Posted June 7, 2006 Seems very sensible to use gaine. Those wonderful UK house built with cables running down the walls with, at best, a bent piece of metal over them for protection and, at worse, just buried in the plaster. Major job to rewire Link to comment Share on other sites More sharing options...
Alcazar Posted June 7, 2006 Share Posted June 7, 2006 Agreed. Not to mention the possible mechanical damage to cable threaded through a rough hole, over the years.My copper pipes even go through PVC ones for protection, here in the UK.Alcazar Link to comment Share on other sites More sharing options...
Gluestick Posted June 7, 2006 Share Posted June 7, 2006 PVC cable buried in cement/plaster will degrade over time, due to the chemical reaction and thus lose insulation capablity.Copper pipes are affected in a similar manner.Thus makes much sense (ease of re-wiring apart), to locate in some form of protective outer sheathing.Most UK cabling these days (and for some years) is carried in plastic conduit, in fact.

Matt Posted June 7, 2006 Author Share Posted June 7, 2006 So even the cabling running to my light pendants in the ceiling void should be in gaine? Link to comment Share on other sites More sharing options...
La Guerriere Posted June 7, 2006 Share Posted June 7, 2006 Yes, if its not accessible. If it's surface run or in the loft I think you are OK Link to comment Share on other sites More sharing options...
Matt Posted June 8, 2006 Author Share Posted June 8, 2006 Can some one tell me the difference between disjoncteurs and coupe de circuit and which I should use Cheers Matt Link to comment Share on other sites More sharing options...
Dave&Olive Posted June 8, 2006 Share Posted June 8, 2006 hi ok disjoncteur is basically a resetable trip, the other is just a fuse.you can you any just make sure the are the correct amps dave Link to comment Share on other sites More sharing options...
Alcazar Posted June 9, 2006 Share Posted June 9, 2006 Disjoncteurs are faster acting, more accurate, (a 10 Amp one will trip at 10.1 Amps, a 10 Amp FUSE however, may carry up to 16Amps before it melts), and resettable.They also, if you use new ones in France, cut the phase, (live) AND the neutral at the same time, so no shocks from wrong-way-round wired sockets etc!Most French installations also have "Disjoncteurs differentielles", which are RCD's, and there are two types of those, IIRC, type A are for circuits with large electric motors on them, eg washer, tumble drier, and some large hobs, (Induction hobs?). Type AC are for everything else.I'd suggest you search out and buy "L'Electricite Pas a Pas", and "Maitriser l'Electricite", both paperbacks from Leclerc, around €5 each, plenty of good diagrams, easy text.AlcazarAlcazar Link to comment Share on other sites More sharing options...
Matt Posted June 20, 2006 Author Share Posted June 20, 2006 If I am running a 20a circuit with a maximum of 5 sockets is it wise to also put a 20a single socket circuit? in the rooms for the use of fan heaters and other high load appliances?

Alcazar Posted June 20, 2006 Share Posted June 20, 2006 My books don't say so. You only need dedicated circuitry if you've got electric heating permenently wired in.Given that each room will have a 20A disjoncteur, that's a total possible 4600W per room[blink]Should be enough for a heater along with smaller items?Alcazar Link to comment Share on other sites More sharing options...
Matt Posted June 20, 2006 Author Share Posted June 20, 2006 My only concern is if I have three sockets in one room and two in another on the same circuit, potentially two high load items? Link to comment Share on other sites More sharing options...
Dave&Olive Posted June 20, 2006 Share Posted June 20, 2006 hi ok no expert here but.... why worry ,,, if you overload a circuit it will trip out to protect the wiring ..........provided you have wired it right. dave Link to comment Share on other sites More sharing options...
powerdesal Posted June 21, 2006 Share Posted June 21, 2006 Its my interpretation that the normes/codes allow 8 x sockets on a 20 amp feed and 5 x sockets on a 16 amp feed, in fact the sockets can even be double sockets which count as one socket for code purposes. This does not help at all if you are putting high load items on multiple sockets at the same time.If you take the system volts as 220, a 3kw heater will take take 13.6 amps at full load, you will therefore be limited to 2 kw of heat in 2 x different rooms at the same time ( total 18.2 amps) otherwise, as Dave said, the breaker will trip.If such a loading pattern is expected you will have to fit a more complex wiring system with individual rooms fed by individual circuits possibly.Regards Link to comment Share on other sites More sharing options...
