	Subject - French Electrics EuroSpark A few questions about the difference between English and French electrical systems. I understand ring circuits are not allowed in France and that the French tend to use more smaller circuits rather than fewer large ones. Help on fuse ratings and cable CSAs would be greatly appreciated. Ryan_J Ring circuits are not allowed in the US either. frenchelectrician eurospark: the french electrical system dont allow the "ring" circuit at all. and it is not the same as UK electrical system and in north america the ring circuit is not allowed at all per nec codes. in North American electrical system ; branch circuits are useally 15 or 20 amp 115 or 120 volts and useally proceted by circuit breaker[s]. [ line to netural] but North Amercian circuits have bigger circits also like 30 amp ,50 amp both are useally 240 volts line to line , single phase Main breaker or main fuse for home useage will be 100 amps or 200 amps some case are larger butfew older homes have 60 amps main devices but no longer legal currently. type of wires in north amercica useally use the romax type useally 14 gauage for 15 amp circuits, 12 gauage for 20 amp circuits. if need more question let us know we can explain more between north america and european verison. merci, marc EuroSpark Thanks everyone. This is very useful to me. I am based in the UK, I didn't know rings were not allowed in the US. I have to say I'm not a fan of ring circuits, in the UK we use 2.5mm cable in a ring for socket outlets fused at 30 Amps. The problem is 2.5mm cable can only carry around 20 Amps in ideal conditions (this is fine whilst the circuits continue to be double end fed as in effect 5mm is supplying the load) I just don't like the idea of a senario where a broken cable can leave a circuit fully opperational but with insufficient cable size to carry the current.
