MegaSack DRAW - This year's winner is user - rgwb
We will be in touch
We're getting some work done at home and as part of that we're getting a water pipe moled in to what will eventually be an office/workshop out building though likely not till the end of the year.
Whilst that's being done it seems sensible to me to get a power and LAN run as well, the question is, would you directly run the cable (4mm armoured and a cat6) at this point [left unconnected at the domestic end until the building is done] or would you run conduit? I'll need to box in the various supplies far end either way but imagine a conduit will also need some extensive sealing to prevent it becoming home to some wee beasties over the intervening months.
Long term i can't imagine me wanting to drag anything else across the way so I'm not sure conduit makes any sense.
Am i being silly discounting the conduit option or is, as i suspect, cable only the way to go?
The only thing i can think of is is the sparky likely to be unhappy with a preinstalled cable and want to pull their own?
(Obviously what i really want is an underground tunnel with concealed entrances betwixt the house and my [s] evil lair [/s] office/workshop, but this isn't practical and would just be one more place that housed hundreds of spiders and that i never tidy up)

Theoretically the cable needs to be specified by the electrician signing everything off. If you run conduit then the he/she can do that later. The conduit will be one piece so only need to plug the ends to keep muck out. Also you'll need two runs of conduit as data should be separated from power.
Not sure how you do it with a mole as the conduit (or cable) should be in sand with warning tape above.
Two replies about number twos out of doors. And there i was wondering how this was "news".

SWA could be laid in the ground. Usually at a depth that would stop it accidentally being dug up, e.g. 450mm.. marker tape at 200mm above ideally.
Do what you like with the cat6.. however personally I'd be making the hole for the power large enough lso install a 22mm pipe duct for the network. Ensure you keep separation to avoid interference on the network.

Ensure you keep separation to avoid interference on the network.
CAT-5 doesn't care if it's next to mains cables (twisted pair is very interference tolerant), but Part P does, so you have to use a separate conduit.....
Also you’ll need two runs of conduit as data should be separated from power
Ah yes forgot about that, the main advantage i could see if running conduit was less digging. Though i should be under the 35m mark anyhow and would be running screened cables in conduit which should be fine under bs en 50174-2.
Edit: Ah didn't realise there was stuff in part p about data cable seperation. Back to the drawing board...

This. 😀
(assuming single phase supply)
Conduit for the SWA, smaller conduit inside for the data cable?? The idea is to separate the data cable (? 30v insulation?) from the power (? 600v insulation?) so that 230v doesn't end up where it isn't wanted. Check with your installer to see if (s)he will sign off on that
That's a good idea of they'll pass it cheers timba
