2.5mm flat cable with a sleeved CPC

[John-SJW]

I recall seeing this a long time ago. Is it still available? Anyone know.

Everything in the UK is done on the cheap. Final Ring circuits, omitting insulation from a cable, poky cheap and nasty consumer units, etc.

You’re right, except for the RFC’s. Nothing wrong with them, done properly.
As for standards, we used to be renowned for producing the best gear in the world.... and not just in materials but labour quality.
It’s all gone to pot,.,,,,all for the ‘quick cash’
theory. And it’s top to bottom of the trade.
Industry today, we’re laughing stock.

So why no cable on sale in the UK? mmmmm

Lack of demand and higher cost?

I am sure the cables would be safe and acceptable for UK use, but why pay more if it is not brining any real benefit. ROI 2.5mm T&E has 27% more copper per unit length than UK T&E (someone might want to check that) and as cable costs are dominated by the copper that is probably an increase in cost to the end user of about a quarter.

And if it's plywood, you'll be right!
Applies to the cross section of timber as well. No one asks for 200 x 47 in the merchants - it's 8 x 2, and the length is measured in 'metric feet'.
When I come back from holiday (remember them?), I don't only come back with enough booze to stock a pub, but also three or four tape measures, which, of course, are metric only.

After we transitioned from imperial to metric it was normal that every tape measure had both metric and imperial measurements, which are dead handy. Notice that is no longer the case so if you have an older one....... Don't lose it

I would be genuinly interested to know what the reasoning/justification was for ROI adopting the same size of CPC and pushing up costs. Anyone know?

I have found nothing in print about it but when I queried my inspector he said it was influenced by EU harmonisation

You are not laughing stock. Still respected. But you are gaining a growing reputation for shooting yourselves in the foot.

6.00mm for a 32A oven? 4.0mm cable can take 37A, unless a long length is used when assessing voltage drop.

Can 4.0mm take 37A when the ambient temp is a 50 degree roof with insulation laid over the top? We've had to derate our CCC fairly heavily because of that yellow death-orb overhead.

Technically it is on sale in the UK. Wholesalers in N. I. stock it. They are playing a growing role in the ROI market

 

[John-SJW]

Would this be in one of the copper shortages, when we were using cable from wherever it could be sourced?

It is no coincidence that T&E with a bare reduced size earth conductor came around the coper shortage of the Rhodesia crisis of 1965.

Why have Ireland gone back to having the earth the same size as L & E?

N Ireland sellers sell to the south cable that is not common in the UK? So they sell to the south, the south's own standard of cable? I know it is made in China in most cases.

Checked, closer to 15%

Almost, then.

Rubber T+E was a good bit previous to that.
..and I'm sure some 7/029 twin had a 3/029 or 3/036 earth.

Discussion about Irish T&E was covered in this thread, some time back, which included some additional information.

I'd imagine they stock it for a couple of reasons.

Many electricians will work both sides of the border - especially those located close to it. Works for the electrician and works for the wholesaler.

Larger wholesalers will also deliver to anywhere on the island as doing so is easy, quick and relatively cheap. No point in touting for ROI business, if you don't keep what they need.
