Which cable types are now required for:

a) nonburied run to shed, some attached to brickwork, some laid on

b) surface clipped run to lighting, some lengths under plants some not.



If there is a risk of damage due to strimmers/ cutters etc then you
need a cable with an outer earth sheath. So that's SWA or SY.

If not then use NYY-J cable.

I hadn't heard of NYY-J until now, why would you use it rather than SWA?


NYY-J used to be sold under the name Hi-Tuff. It's cheaper than SWA,
does not need glanding off and is ideal for outdoor surface mount jobs.
It is not suitable for direct burial in the ground unlike SWA.

He could shove it down a length of galvanised pipe for the ground level
bit. Or is that an offence nowadays?
