Cable for video doorbell

[Mr Sparkle]

Transformer has been placed in consumer unit and it has power.

To power the 0-24v video doorbell can I use 2 core flexible cable such as 1mm or do i need to use 1mm flat cable.

Also is 1mm cable overkill? Could i use 0.75mm?

Doorbell is less than 2m away from transformer

Since in a consumer unit the cable must be 230 volt rated, even when only carrying 24 volt. But as long as 230 volt rated not a problem.

So am i right in saying that i can use 0.75mm or even 0.5mm 2 core flex cable then?

In the main under 1 mm² is not rated at 230 volt, you can use thinner if rating is OK, but unlikely it is.

Yes, 0.5mm² 2 core flex will be fine...

0.5mm² 2 Core PVC Oval Flex White - Cut to length or 100M Drum
