When is a new circuit not a new circuit?

I replaced my failed washing machine over the weekend with one that includes a variable speed motor drive. I don't think the instructions mention it, but I know it should be on a type A rcd

Or a Type B if it is inverter driven?

Yes, it's getting complicated.

On a point about prosecution, that isnt going to happen. Current Building regs are not adhered to, and nothing is done because there arent enough Inspectors, and when they do find failings, it is rare for there to be any action against the miscreants.

I'm currently working on a new build school. The stairway lights are too low, so we need to lift them up around 800mm. The walls are double plasterboarded/staggered joints etc to keep their fire integrity. The National Company who are Managing it have told the plasterers to cut out slots to allow us to fit more conduit. The plastering company said it will lose the fire rating if they do that. The Managing Co. said dont worry, it is us that are signing off the compliance, and it'll be fine. Of course, one would think , after Grenfell, that there woudl be full compliance with Building Regs, but as I've found out, that doesnt happen when they want something doing quickly, and they can self-certify.

In which case, "we", as professionals, should be reporting such behaviour to the appropriate body.
