Discuss Advice wanted - unhappy with rewire in the UK Electrical Forum area at ElectriciansForums.net

Would you consider a domestic installation as unlikely to need consideration for high integrity earthing unless there is a specific reason (e.g. medical equipment)?
Yes, if a circuit was intended to supply alot of high earth leakage equipment or upon measurement leaked 10mA or more then I would protect that circuit/ split accordingly eg. with type A/B RCD. And high integrity earthing.
But like you mentioned this would most likley be Radials with a seperate earth run as a ring.

I dont think its really necessary to install high integrity earthing in most domestic cases, but it is important to protect with the right type RCD to avoid nuisance tripping, and make sure the RCD would not be effected by the leakage and operate correctly
