ive got a 3month old, thats why I'll put ALL skts on 30mA,ckr coulda developed a fault in 15th or 16th and was fine without an RCD.(gas hob, elec dble oven)
I really cant believe none of you guys ever use 25a MCBs.... mate at work wouldnt believe me they existed till I showed him one.
dont want smokes tripping off unknowingly(ref sentence 1)they will be linked to landing light, non 30mA.
100mA is something Ive done quite a lot in certain properties where i feel vunerable people live(ie, elderly etc) just that added edge without the nuisance of excessive tripping, (Im TN-S btw)
another thing I will be doing is something I used to do for houses in the sticks and limits the shock hazard in the bathroom is to down fuse the bathroom light from the shower circuit and fit an emergency pack, power cut when your in the shower you still have a light. plus under fault conditions you only have one MCB(40A) to trip rather than 2,(40+6=46A)!
