steady on. it's only 50 years since we went metric. ( a backward step, IMO, I'm still 5'8"and 12st. 10lb. ).on a side note , I think it’s nuts that we the u.k haven’t adopted twin @ earth with a sheeved cpc Yet.
no more Faffing about with little pieces of earth sleeve
The UK earth sheathing looks so amateurish and cheap.on a side note , I think it’s nuts that we the u.k haven’t adopted twin @ earth with a sheeved cpc Yet.

The metric system is superb. I am 183 cm high and 76 kg.steady on. it's only 50 years since we went metric. ( a backward step, IMO, I'm still 5'8"and 12st. 10lb. ).
I wouldnt say the earth should be the ‘largest’ but imo it should be equal size to phaseThe Irish cable is superior for sure. All conductors being insulated with the CPC the same size as the L & N. Does the cable conform to the UK requirements?
As a kid I recall an old electrician say, "the largest sized conductor on a circuit must the earth cable". How matters have changed.
I've always wondered this myself. I gues its just easier & cheaper for the manufacturers to omit it, if its unrequired.on a side note , I think it’s nuts that we the u.k haven’t adopted twin @ earth with a sheeved cpc Yet.

He was implying the earth must not be smaller than any other. It can be larger, but never smaller.I wouldnt say the earth should be the ‘largest’ but imo it should be equal size to phase
That I agree withHe was implying the earth must not be smaller than any other. It can be larger, but smaller.
Cable manufacturers would disagree, that means more copper! ?I wouldnt say the earth should be the ‘largest’ but imo it should be equal size to phase
Everything in the UK is done on the cheap. Final Ring circuits, omitting insulation from a cable, poky cheap and nasty consumer units, etc.I've always wondered this myself. I gues its just easier & cheaper for the manufacturers to omit it, if its unrequired.
impossible for me to visualise those measurements.The metric system is crap. I am 183 cm high and 76 kg.
After all this time? Metric is easy. You just gave a simple easy e.g., as well. Very easy. Learn it, it is simple and quick. Everything matches.impossible for me to visualise those measurements.
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.
