Re: earth leakage
The 17th edition will require all circuits where the cables are concealed in walls or partitions less than 50mm deep and not protected by earthed conduit etc, to be protected by a 30ma RCD. This will apply to lighting circuits as well.The adopted method of complying, may be the use of individual RCBO's (combined rcd/mcb)to minimise the inconvenience and dangers of tripping. The use of SWA cable for circuits would not require RCD protection.
Hope this helps
