[QUOTE="steptoe, post: 3106, member: 7"] to meet 17th, and have protection within the scope of not causing nuisance tripping..... HO HO HO well yes and no then.... do you know of a suppliers that do a 30mA rcd with a time delay function? like the more common 100mA (T or S) version, I have brought this exact situation up numerous times to various organisations with no definitive answer as yet. simple answer is YES you must provide 30mA RCD protection for the sub, but you must be able to provide this without causing un necessary tripping to other circuits,. how to do this and ensure discrimination between tripping devices with what is on offer with a BS/IEC/EN mark at this present time is beyond me. perhaps some1 that makes the regs will eventually come up with a reason/explanation as to why every single install like this will always have a deviation. SORRY to go on, but dont stress too much about the regs, just mark as a deviation, its not a fail, or anything like it, as long as you prove its safe and if possible mark the wall as such, ie, "ELECTRICAL CABLES - KEEP AWAY" (or whatsoever it is) you have fulfilled your obligation under the EAWR. HTH, remember, its only IMHO Albert [/QUOTE]
