What size conduit

[padstar]

Hi I have a EV charger to be installed. The cable will pop through the external wall drop down a conduit approximately 1.5m long then run under the floor void back to the CU.

Charger requires a 6mm twin and earth and I want to run a cat6 with it.

If the sleeving is removed to the section run within conduit will that all fit down a 20mm tube?

Personally, I wouldn't' bother with the conduit and just use a combined cable like this...

EV-Ultra SWA Cable 3 Core 6.0mm + Cat5 Enhanced | DC (EV-ULTRA3C6.0CAT5SWA)

I looked at the combined cables but surely they are useless at the other end as the data element needs to go to 1 place and the power another?

Are they only good if you have both power and data at both ends?

Don’t think you should do that.

Don’t think you should do that.

If the SWA is correctly installed, there is no regulation preventing the singles continueing in other containment if appropriate.

EDIT: Cat 5/6/7 cable may only be run in the same containment if fully rated for mains voltage.
I've confused thread with another. I'm getting a little confused, are you doing the whole run with T&E but the vertical part in conduit? If that is the case I'd suggest a bigger conduit or trunking and not split the cable. Silly as it seems; it may be argued the earth wire in T&E is too small to be run as singles and of course it's not insulated.
