[QUOTE="kme, post: 215888, member: 113"] The 0.2 sec. comes from it being in Zone 2 of the swimming pool (socket outlet) mate. I prevaricated a little as to its required disconnection time, and decided that, as the spec. in 702 calls for an RCD with 40mS @ x five delta n ; so I thought that, without definitive data to the contrary, 0.4 can`t be the disconnection time in a swimming pool area; it must be at least 0.2. I`ve got curves here (somewhere ;) )for 3871s - I`ll determine the figure from that. I`m not overly concerned, TBH.....Its going to be replaced in short order by a 61009 - maybe even a pair in series, for redundant protection. n.b. Snakehips - you had copy of fleamail?? [/QUOTE]
