Cabling where practicality goes a miss

[cliffed]

Would any of your guys actually run t&e,between the clips of the guttering,around the front of a house, porch like extension.
Seems the only way to do it,the cable would be hidden ...but...what’s your take on this.
It’s gonna be a rubbish job anyway.

I see a lot of sy,yy & cy cable installed.
At least t&e is a recognized and approved cable.

It might be recognised and approved but that doesn't automatically make it suitable for any application. It's less suitable for external use than other cables.

At least t&e can be considered and disregarded due to the fact it is an approved cable..
Whereas sy type cables don’t.
Basec have condemned their use.
Just because something is widely used doesn’t make it right.
There has been many incidents involving products that have been widely used that shouldn’t have been.

Oops - can I blame spell check?

Not aware that BASEC have condemned the use of SY cables.
Last year they were asking for input on specifications for control cables, specifically CY, SY and YY cables.

I read an article that they had published stating that these type of cables shouldn’t be used..
I got involved in a job where sy cables were being run all over the house as submains to all the db’s..
I objected to their use and as support I sought advice from Basec..
Dr Jeremy Hodge the Chief Executive emailed me and gave me the information to support my objection to their use..
I still have the email from basec if it is of any interest to anybody..

Prysmian technical also give some very good information about these type of cables..

Should SY, YY and CY Cables Be Used in Electrical Installations? - https://www.whyprysmian.co.uk/sy-yy-cy-cable.html

I was contacted by BASEC for my input on a new specification for these cables February last year.
Seems they introduced the new specification 2 days ago.
New testing and certification scheme launched for YY, SY, CY control… | BASEC - https://www.basec.org.uk/news/2019/4/25/new-testing-certification-scheme-yy-sy-cy-control-cables/

Brilliant and about time too..
Hopefully we will soon be able to specify these cables without any issues..

I’m going to send them another email enquiring about what manufacturers are going to be getting cables specified.
Thanks for the update

Lots of decent info here

But you're the only person who has raised the subject of SY etc in this thread? NYY-J has been suggested which is made to a BS-EN standard so is compliant for installations subject to bs7671.

Which standard please?

What is the issue with being the only person?

No

Not sure if you are being serious, but anytime I see T/E installed externally, I always prepare myself for more bodges inside the property.

I frequently see people on their mobile phones when driving, but it doesn't make me think that lots of people are doing it so its okay!

20 years ago it was accepted practice, regs changed the same as with seat belts........

I did the 16th edition, and I don't recall 20 years ago T/E being okay to install outside, but with you saying that and someone already liking your comments, then perhaps I must have been doing it wrong back then by not installing it outside.

 

[mattg4321]

I don't think I've ever installed T&E outside with no containment.

Proper lash up in my opinion.
