Discuss Split load dual RCD in the Electrical Forum area at ElectriciansForums.net
It will depend on the installation requirements , some circuits will not require rcd,s if the wiring is in trunking , conduit or otherwise protected ;to keep answer simple because it's getting late lol.Why do the wholesalers still sell them when to adhere to the 17th were using dual rcd boards
Yeah one of the new regs is if cables are less than 50mm deep or are not mechanically protected they must be protected by a 30ma rcd. Make of that what you will lol.Thanks a lot interesting.I would have thought RCD on lighting would cause a lot of nuisance tripping low voltage lighting etc,but I must be wrong.I don't do domestic work but as far as I know in Ireland,lighting cct in bathrooms and external lighting now need to be rcd protected,along with sockets and showers which always needed rcd.I think a lot of guys are just fitting a rcbo on every cct.It seems a bit overkill to me,but I'm open to contradiction..
That'll probably come out in the next edition.I don't find lighting nuisance trips RCDs - they normally trip the MCB.
RCBOs are slowly becoming cheaper so I feel that within a few years a 10 way RCBO board will be about £80-£90 which with the benefits of not taking out 5 circuits in the event of a fault will work out better for all.
They just need to give us more head space in CUs
Got your facts mixed up there sky.A split load board is a consumer unit normally split in half (but in the same enclosure) if it was a ten way board you would have 2 banks of 5 MCBs, Each set of 5 MCBs would be protected by 1 RCD (so 2 RCDs in total)
