My question relates to the latest regulations (BS7671:2018+Amendment 2:2022) and RCD selection.
I have an existing installation with an upfront 30mA type-AC RCD.
I am quoting for some work where there will be some electrical alterations for a new kitchen. No new circuits! Mainly some new sockets and LED lighting and relocating a cooker cable. So DC components will be introduced.
Is there a requirement to upgrade the RCD to a type-A RCD to comply with 531.3.3?
Are others anticipating fitting type-A rcds on their minor works now e.g. 4 new downlights in bathroom?
The current board is obsolete so either I put a different manufactures kit in to the board or a new consumer unit. Understandably the customer is reluctant to spend any more money
