[QUOTE="Mr Sworld, post: 17326, member: 184"] You need to minimise the posibility of one fault knocking out an entire house. Hence the idea of having one rcd for upstairs circuits and one for downstairs (or for 3 story houses having a third rcd 'side'). See 314.1 As for rcd's on cables less than 50mm, this really only applys to domestic. Comercial and industrial locations are generally under the supervision of a 'qualified' person so 522.6.7 superceeds 522.6.6 [/QUOTE]
