or a bit of 10.0mm T/E left over from the last shower installation.

Wow, just checked prices online, NYY-J is a lot more expensive than SWA

I find that hard to believe .... What length do you need and what size cores?

Does this really need an additional DB? Can you not install a new final circuit to feed the sockets and extend a local lighting circuit to feed the lights?

I like NYY-J much easier than swa but the chances of getting the length you require instead of a drum is remote whereas swa you can often get a cut length.

Some wholesalers don’t seem to have any trouble getting cuts of NYY-J, I think a lot of the time the staff just can’t be bothered to deal with the request when they’ve got SWA on the shelf on cut already.

I've never used NYY-J cable, interesting. Does it come up to BS standard for a general installation, lights, sockets, etc?
I come across quite a bit of SY cable supplying 3 phase machines and external air con systems. I thought it was a bit of quick way of going about things, especially when not glanded correctly, as is usually the case....and have used it for feeding from panels or control units.
Is there not an argument for all the Y's being regarded as control rather than supply cables?

These cables are nothing like YY, CY or SY. They are similar or the same essentially as High Tuff cables and comply to IEC60502 which is referred to in BS7671.

I'd never even heard of this "NYY-J" before today. It sounds like the old "pre-wired conduit" that was around before my time.
I don't see that it has any benefit over any other existing wiring system, such as flex in conduit. It sounds to me like an answer to a question which nobody has asked.

 

[westward10]

Nothing like pre-wired conduit or flex contained in conduit. It has low mechanical properties but most cables do but has good resistance from solar damage.

You're still not selling it to me - what can NNYJ cable do that SWA or black PVC conduit can't and how do you terminate this new cable?
So it's got good solar resistance (like black PVC conduit, SWA, even steel conduit); if you've only got a short run to go outside, what do you do with the thick sheathing on the rest of the run?

 

[westward10]

Not trying to sell it to anyone.

H07RN is my go to cable for wiring machines

Pros and cons all round. Depends on the situation, really.

Hi-Tuff isn't uncommon here so cut lengths are often available.

There are pros and cons to each cable type, which aids in their selection, but I don't see where this NYY-J could be useful to me where nothing else exists that does it better.
