teresa Dipple Posted April 13, 2006 Share Posted April 13, 2006 Can anyone clarify the difference between the usage of Type A and Type AC interrupteur Differentiel which must now be used in all new installations. I thought Type A was for all power sockets and Type AC for lighting and heavy current users like cookers, washing machines etc. where the level of protection required is less. But in different books i have seen sockets connected to both. Link to comment Share on other sites More sharing options...
La Guerriere Posted April 13, 2006 Share Posted April 13, 2006 The basic idea of an ID is that if there is an imbalance between phase and neutral due say to an earth leakage it will trip. A type A detects AC only, a rtpe AC detects AC and also DC leakage. Type A is the general one for power and lights, Type AC is for cookers , washing machines etc where there might be a DC leak. At least I think that's how it goes. Link to comment Share on other sites More sharing options...
La Guerriere Posted April 13, 2006 Share Posted April 13, 2006 Buggerit, wrong way round again, it's AC for general, and Type A for cookers and washers. Link to comment Share on other sites More sharing options...
powerdesal Posted April 14, 2006 Share Posted April 14, 2006 I was (am) also confused about the type A / type AC breakers, I tookadvice from a Belgian electrical /electronic installation contractingcolleague who said he always uses type AC throughout, never uses thetype A.I presume Belgium has the same codes/normes as France and, unless thereis info to the contrary I must presume he knows what he is doing.Regards Link to comment Share on other sites More sharing options...
