YY cable size

[Sadruddin]

Hi. I'm wiring in an MVHR unit, and raised a thread here

https://www.diynot.com/diy/threads/wiring-in-an-mvhr-unit.561685/

about it. I was suggested YY cable.
The power requirement is shown in red, here



By my calculations, I'm needing less than 1 amp, so 1mm cable would work, but I'd run the power separately.

Is that right, please? Thanks.

The linked cable in the other thread will be more than adequate, but you might not need 7 core.

but I'd run the power separately.

Depends on the location of things, I suppose.
