Good day all,
I have a client who wishes to replace lighting within the building and the simple question I have is do I have to allow for RCD protection for altered circuits as per 18th edition or can I omit the RCD as we can treat it as retrofit? We have an old type of the fuseboard so I would need to allow for separate enclosure fitted with RCDs. Cheers everyone!

Domestic?
If so, then you can do a like for like replacement without changing the circuit protection. I would class replacing old luminaires with a newer design as 'like for like'.
Commercial? then there is no change to the requirements. Ask for the Company's risk assessment to see if they would like the circuit to be RCD protected.
