Got a job where the customer has ordered 35m of 10mm 2 core SWA, went to day to install and was taken back in how thin the cores seemed, double checked his paperwork and he ordered 10mm.

He got it from eBay from a electrical seller, (trade seller)

Any one come across particularly thin cables recently?

Popping back in the morning with take the info from the cable

The sector shaped cores start at 25 but the 10 or 16 these days tend to have shaped strands so that they compact down smaller without the gaps between the cores you get with round strands.
I'm not sure quite why though

Ahh Doncaster Cables (someone mentioned them, and forgot to quote / cba to find it again) once reliable, now the drums break easily :(

Did anyone else get that DVD called 'fake britain' sent to them from there scam? It's only like 10mins long, but the ECA sent me it and my god it's an insight. Criminals will try out these days.

Formed (sector) conductors appear smaller than circular ones that might be more familiar in appearance, because there's less airspace between the strands. It's very difficult to measure the CSA because the strands aren't circular, although if you can cut a chunk off you can weigh them. Does the cable marking claim it to be 10mm?

no Lucien..
CSA is all about the conductor area...
not airspace between strands...

was it to do with so called 2.5mm CSA...which in reality turns out to be 2.2mm CSA....or thereabouts...
or maybe its the copper coated training cable that has been doing the rounds?...

As others have already said, get your own cable.
I certainly wouldn't buy it off ebay from someone with a user name of gerbil007 and whose trading address is a house on a new build housing estate! :)

I don't get your point here, Glenn. What I meant was that shaped conductors look smaller for the same CSA because there's less airspace. But unlike circular conductors you can't prove what the CSA actually is by measuring the strands with a mike.

We had some crap cable from a reputable wholesaler some years back.
A 35mm lug fit onto the (supposedly) 50mm cores.The outer sheath was brittle and split if you tried to bend it. We also had splits in the conductor insulation. The whole construction of the cable was shoddy and unsuitable, this was evident just by looking at it !

This stuff had BS numbers and BASEC approved stamped all over it.

Get your own cable and save yourself some nuggetache.

Should the armour of an SWA carrying twin and earth cables also be earthed (with banjos etc)
I assume said contractor is part of a Part P scheme (NICEIC, Napit, few others..) in which case complain to them. They'll investigate (in theory)...
