Discuss 2.5mm flat cable with a sleeved CPC in the UK Electrical Forum area at ElectriciansForums.net
I believe the Australians do the same but use stranded cable. That must really push up the costs.
Would this be in one of the copper shortages, when we were using cable from wherever it could be sourced?I remember back in the late 80s probably where we used some 1.5 and 2.5 with an insulated cpc. No idea of the manufacturer and I had kept some but no idea where it is now.
And if it's plywood, you'll be right!I use metric for precision and imperial for rough measuring. e.g. a 2400 x 1200 sheet board I call an 8" x 4".
No, as the CPC never carries the current for any significant length of time. Even for the odd case of a N-E fault and then an open N you would be disconnected on the RCD in most circuits so the CPC never needs "overload" protection, only ever fault protection.So it needed to be the same size as L and N. Seems modern disconnecting safety devices have changed the view.
You’re right, except for the RFC’s. Nothing wrong with them, done properly.Everything in the UK is done on the cheap. Final Ring circuits, omitting insulation from a cable, poky cheap and nasty consumer units, etc.
Lack of demand and higher cost?So why no cable on sale in the UK? mmmmm
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 itAnd 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.
I have found nothing in print about it but when I queried my inspector he said it was influenced by EU harmonisationI 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?
You are not laughing stock. Still respected. But you are gaining a growing reputation for shooting yourselves in the foot.it’s top to bottom of
Industry today, we’re laughing stock.
6.00mm for a 32A oven? 4.0mm cable can take 37A, unless a long length is used when assessing voltage drop.
Technically it is on sale in the UK. Wholesalers in N. I. stock it. They are playing a growing role in the ROI marketSo why no cable on sale in the UK? mmmmm
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.Would this be in one of the copper shortages, when we were using cable from wherever it could be sourced?
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.Technically it is on sale in the UK. Wholesalers in N. I. stock it. They are playing a growing role in the ROI market
Checked, closer to 15%ROI 2.5mm T&E has 27% more copper per unit length than UK T&E (someone might want to check that)
