Is there a requirement for a domestic install to have one master switch for the installation?
If I had a second consumer unit added above the existing one, due to lack of space for anything wider, would it be valid just to have their respective main switches? The second CU would be for RCD circuits, effectively providing a split load arrangement.
I do not have a main isolator at present (any idea what Seeboard's reaction is on being asked to fit one?).
An alternative could be to use one of the RCBs for the second unit, meaning the main CU switch would operate both?
I'm not doing any CU changing myself but I wanted to be sure of what is good practice before prompting the electrician.
Thanks,
James
