[QUOTE="kme, post: 8876, member: 113"] Agree ref all skts on RCD - makes sense. Yes, ckr could`ve developed a fault before; but that is the sort of comment that, TBH, I`d expect from a customer, not a sparx. Honestly have never seen or heard of 25A MCB. Maybe I`ve had a sheltered life........ "smokes tripping unknowingly"? The only reason they should trip is if the cable gets damaged; or an alarm goes u/s! If the power DID "unknowingly" trip, then 1) you "should" spot it on your `weekly` look at them, and 2) the backup batts would keep them working; albeit with an occasional "beep", which ought to alert you to a problem anyway. The 100mA - I`ve heard of it done, but, in a situation as you describe, I usually fill the board with rcbo`s. As for the shower - the em. light. Yes, I can see the logic in that; but I`m not that struck on the "single mcb" argument. There appears to be a discrepancy in the argument; but my alcohol-fogged brain is starting to wilt. Leave that bit with me, and I`ll be back afta. :x ; ) [/QUOTE]
