What would you use?

If it is not inverter driven than CY or it’s equivalent polyurethane coated version.
for a stationary motor, singles in conduit would be fine (tri rated)

edit, I did not mean CY, I meant YY. Oops, CY is screened similar to Sy and not required unless there is an emc issue.

That’s my point. You did not know the application so unsure why you stated it was not fit for purpose.

What would you use?

One that is recognised by British standards

SY, CY and YY cables are not manufactured to a specific British, European or international standard so in most cases it is not possible to demonstrate the performance safety standards required to satisfy the Wiring Regulations.

I would say 90% of times I have come across braided style cables they have not been installed using the correct glands.
Near every time they have been installed like the picture using a stuffing galnd Or no gland at all

What wiring Regulations?

Again, you are making the assumption that it was used in a fixed installation. 7671 does not apply here.

Surprised by this TBH.

Is there a 'correct' gland for this stuff? I've never installed any of it, but have performed maintenance and repair on installations using it, and the only glands I've come across are standard stuffing ones.

Yes proper sheild cable glands are available but very rarely used.
They look a bit like SWA glands when done

For EMC compliance, the braid needs (should) be taken back to the source (drive)

So I’m calling out -------- again unless these are intended to terminate onto the gland plate of the drive (which most don’t have).

Also these use pigtails, also VERY poor for EMC compliance.

Sorry…

This is the kind of gland I was thinking about

Yes there are various types of gland available which connect the braided shield by various means. Some required the braid to be pigtailed and clamped in a slot in the gland while others work more like an SWA gland.

Stuffing glands can also be the correct gland depending on the application.

For some installations the braiding will need to be connected to earth at one end of the cable and isolated at the other end.

I haven't made any assumptions as to what YOU used it for, I said that I basically wouldn't use it.

The uncertainty is how much you might rely on the braid either as a CPC or as an earthed 'armour' to allow routing out of a 'safe' zone. Now the braid resistance of all but the shortest length is not really low enough for a CPC on its own, (the braid resistance is not a well controlled parameter) and rather like cables protected by thin foils, there is a risk that if the cable was stabbed by a nail or similar, that the braid wires might just burn back from the point nearest the damage without actually blowing a fuse. So if you want to route it 'out of zone' into places where nail and screw damage is likely, especially without RCD protection, then perhaps it is not enough.




The IET's supporting guidance states: “For the purposes of ensuring compliance with BS 7671, the installation and use of non-standard cables, such as SY, CY and YY cables is discouraged.

I've had one of those in my SWA gland box on the shelf for years. No idea where it came from, and, up until today, no idea what it was intended for.

"Isolated" being the operative word. Not waving around in space, a couple of mm from 400V terminals, like in the OP for this particular sub section of this thread.

Let's not turn this thread, if you want to debate these cables which has done many times before start another thread.

Now I know this one may not count as it was in Spain, and everyone knows the quality of the electrical work over there but this was on a main public street on the main road into town

Thats my daughter in the picture

I had to have a look in the cupboard didnt I! as it was wide open and im never off duty! : )

Looks like a three phase connection with the cover open, terminals accessible to any no. of small inquisitive hands

Unbelievable! It was humming so obviously live

Shut the door and tried to wedge it, told the reception staff in the hotel they couldnt give a monkeys

That would be unforgivable in the UK

I just came back from Croatia, Serbia, Montenegro and Italy…. And didn’t see anything as dumb as that.

France and Spain seem to be the worst for dodgy electrics…. But I’m not that well travelled. Just my observations.

I'm worried we're catching them up, fast.

From extensive time/travel in Spain I have to agree that some of the stuff "on the street" is highly accessible and dangerous. Some installations are downright funny too! Street boxes without lids are commonplace and in many places the supplies for every imagineable use are simply various cables bundled up with cable-ties and hung on the outside walls just above head-height.TBH, I've not heard of many deaths caused by such sloppy electrics.
