Coding of non bs7671 cables

[Ian1981]

As title suggests, how many people carrying out EICR code the use of non compliant cables or at least cables not included in bs7671 for fixed wiring such as SY, YY cables.
I see more and more of this type of cabling used for the fixed wiring to anything as a supply to a socket outlet, to a supply for refrigerator units.

Appreciate people’s thoughts and opinions on the matter.

That's a new one! I normally see people put earth sleeving on twisted up braid.

These people are out there !!

Is in a lift motor room, they have also done it across an isolator.

Just out of general interest but RS SY cables are ok for 'fixed installations' according to them.

I questioned this with RS.. They say it's an error and thanked me for pointing it out.

So they are unsuitable for fixed wiring?

I think this is what they are going to change it to.

Note
SY control cables are not suitable for fixed wiring applications requiring compliance with the requirements set out in BS7671.

I’m struggling to think of an application SY is actually suitable for!

We use it a lot in telecoms as it is very flexible and has better mechanical protection than double insulated. SWA can be tricky to get into some of the areas and equipment that is used, SY just fits straight in with very little manipulation.

I like working with SY apart from the braid sticking into the end of my fingers... Had it under the finger nails more than once...

Also very good for connecting to equipment where a bit of free movement is needed or where there's vibrating equipment.

Those are the normal reasonings but other cables are available. It’s completely useless in the wet or outside and is a terrible cable for VSD use.

What about FP200 etc then?

 

[Spud28]

Been asked to look connect a portacabin that is supplied by SWA to an isolator, whereupon SY has been used over a 5m run in the fabric of the cabin to supply a DB. The cable calcs all work out except for the use of the SY. Part of me thinks change it, but part of me thinks that copper is copper at the end of the day! What would you do?

 

[telectrix]

connect it and just make a note on your EIC that you don't consider it ideal.

 

[westward10]

Make a stand for the people

What about FP200 etc then?

What about it? It is manufactured to British standards and BASEC approved.

 

[Toneyz]

What about it? It is manufactured to British standards and BASEC approved.

Is it recognised by BS7671?

 

[davesparks]

Is it recognised by BS7671?

Yes because it is manufactured to British standards and BASEC approved.
The problem with SY YY CY etc is that it’s not manufactured to British standards, it is manufactured to foreign standards
