[QUOTE="ericmark, post: 71202, member: 3407"] I would consider using biggest MCB but there are a few points. With RCD this no longer applies and in a bathroom 12 volt is maximum voltage not 50 so should it not be: R = 12v / Ia ? I can't find formula under 701 in 17th and both 12 and 24 volt AC are given according to zone. Idea is of course that voltage over 12/24/50 will trip MCB and I am sure not 50 volt for bathroom?
