[QUOTE="Phoenix, post: 495334, member: 8133"] The ones I've seen available in this country were SPSN. (Single Pole Swicthed Neutral). I.E They break both conductors, but only the current on the live side flows through the coils and bimetalic strip that can trigger the tripping. I have a feeling in france they might be true DP as they are less concerned about us on the importance of polarity! Hager were trying to market SPNSN to housing associations around the time the 17th edition came in, on the premise that faced with a tripping issue, the tennant could phone up the property help desk, who would follow a script to advise them to switch off all mcbs, reset and bring in one by one, etc. Following them to be without only one cirucit and the electrician to be sent out doing normal working hours, instead of out of hours. It appears that they were not sucessful in their marketing! [/QUOTE]
