NYY-J Tuf Sheathed Cable in sheds and garages

Just doing a quote for garage and shed wiring, plus some outdoor sockets. In the past I have gone down the route of using plastic conduit to protect cables.

I was thinking through the options and I am now considering NYY-J Tuff Sheathed cable as a good alternative.

I am thinking

For external sockets people don't really want 20mm conduit running around the bottom of their house and this at the bottom of the wall would be less conspicuous.

Shed wiring always seems expensive compared to the cost of the shed, moving away from conduit makes it easier to tuck cable in to corners and would save time.

In my opinion at least cables should have some level of protection in garages. Plastic conduit done well looks good and provides good protection, but again is quite time consuming if the cables are concealed over the entire run. Some installers just run conduit to ceiling level but in my opinion this doesn't look great and with people using ceiling space for storage the cable is still exposed.

Just wondering what others think.

  • pity it doesn't come in larger sizes

    It is manufactured in larger sized - in compliance with the Irish Standard IS 273. It's just out local standard BS 8436 that seems to put a 4mm² limit on things. There is a potential issue keeping the energy let-through below what would vapourise the aluminium tube, which would be more difficult with larger MCB/fuse sizes, but the Irish seem to be able to cope with that and I think their laws of physics can't be that different from ours.

  • Don't they do 6.00mm in NYY? I thought I'd had some from my wholesaler in the past.

  • Sorry yes they do, I was talking rubbish. It's more or less the same size as an armoured cable and a little bit more flexible.
