NYY-J Tuf Sheathed Cable in sheds and garages

Alan B

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.

    In the old days we'd routinely clip T&E to the surface in sheds and garages, sensibly placed of course - and never had damaged cables as far as I recall. It's actually pretty tuff as far as normal knocks and bumps are concerned. No harm (other than to the customer's pocket) to go up a notch though.

    I sometimes use BS 8436 cable for simiar situations - I suspect it's thinner than HiTuf, so easier to handle and tends to stay put when bent so easier to dress. Clipped using the PVC covered copper P clips usually used for FP etc, it looks neat and meets the fire resistent support requirements.

    Interesting idea, pity it doesn't come in larger sizes as it could be a useful alternative for getting garage submains through houses. With EV charger installs I seem to spend my life trying to work out how to upgrade garage connections when the consumer unit is on the wrong side or more likely in the middle of a house.

    Quite often end up in a sittuation where the customer doesn't want an SWA cable running down the outside wall of their house, RCD protection then causes issue with selectivity and getting SWA in to their lounge wall would be challenging.

    6242Y clipped direct in sheds is good. Easily installed and inexpensive. Blinkin ek! it's only a shed.

    Customers can be a pain in the ass. They don't want to see externally run cables but tolerate outside rainwater downpipes, oil pipes, gas pipes and other clutter. And inside they tolerate central heating pipes, boiler pipes, water pipes. gas pipes and radiators etc.

    A customer last week did not want surface cables run on the side of his house to a newish rough conservatory, even though the side of the house just ran next to a hedge. He wanted the cables run inside. "Why?" I asked. "Well because it's always done like that" he said. Then he queried the bill at the end due to the extra labour.

    The same customer was told that the two new sockets were fully rated if he wanted to plug in an electric heater. "Oh" he said, "we won't be using them for much".

    Customers are idiots in many cases.
