12v Fan over Bath

I suppose, am I allowed to say its only a little bit of a no-no

In the term "all" circuits in a bathroom must be RCD protected; does that include lights? More importantly, most fans in a bthroom run off a lighting circuit. Does that mean we will now need to run a separate RCD protected lighting circuit just for bathroom lights and attached accessories?
That will conflict with smoke alarm regs (should not be on an RCD circuit) where the lighting circuit with an RCD also powers a smokey?

I could also envisage issues with lighting tripping the RCD that controls most of the socket outlets too. We would get very close to the situation where the incomer is a 30mA RCD and all circuits are protected by it - but that has its own issues re a single point of failure....

presumably it will be better to fit RCBO's.

Are 6amp RCBO's available?

If you fit an MEM RCBO pod to a 6A MCB then yes, but if there is demand for them I'm sure that RCBO manufacturers will start making them.

Why not just fit an RCD spur fed from the lights to feed the bathroom lights?

If you fit an MEM RCBO pod to a 6A MCB then yes..

Hooray for MEM RCBOs!

AFAIK you can get 6A RCBOs,
Picking up on what TTC said, I don't like the way they used the term "All circuits" either. If using SELV, RCDs as I said before are pretty well useless anyway. I'd prefer to see it go the way of SELV lighting in a bathroom.
