What cable for powering external blinds?

[Thorfun]

our external blinds have been put up and I need to get the cable to wire them up. I need 3-core & earth cable. The seller told me that I need 0.75mm² core cable. The motor is a Geiger GJ5606k and below is the wiring diagram:

 

 

the cable will be external to the fabric of the building but will be up in a void behind the head unit of the external blind so 'should' be away from weather and UV but the instructions above say to not use PVC cables.

 

anyone know what cable would be suitable? and can confirm if 0.75mm² cable is correct? I kind of want black cable so it's hidden more from sight if I look up behind the cladding and a white cable is more likely to stand out.

Put the correctly specified cable in trunking.

you read my mind Ian! already ordered 20 x 2m lengths of 20mm trunking. figured I'd run that through the wall and then the cable in the conduit and I can then foam up the conduit to maintain a semblance of airtightness. 🙂

Motor only pulls 0.4A. 

Inrush current is X1.2

So half amp.

There are a number of cable size calculators online that allow for the installation type i.e. buried in insulation.

But 0.75 should be fine.

thanks. the cable will be in 20mm conduit but foamed at each end. the conduit will go through my internal PIR so the cable itself won't be buried in insulation per se.

so this stuff https://www.tlc-direct.co.uk/Products/CA0dot75F4B.html should be suitable? how about being outside albeit under cover?
