Which cable types are now required for:

a) nonburied run to shed, some attached to brickwork, some laid on ground under plants
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.

If it's buried under plants, doesn't it have to be in conduit or
trunking to avoid damage from spades and forks?

Seems to me that "some laid on ground under plants" is a little unclear.
Does it mean only on the surface under the top growth of a plant?
Trouble is, it wouldn't take long to get hidden by fallen leaves and
other stuff, perhaps making it vulnerable to a spade.

I thought SWA was specifically for that. I just wondered if anything was also acceptable but of course it's not.

I see a fair bit of controversy over SY. This job has to be 100% to all standards, so looks like the non-plant on-wall areas will be NYY-J, and the under bushes one SWA.

Thanks folks
