1.5mm T&E or 1.0mm T&E?

We would run a 4.0mm radial off a ring, which explains the 32A, however new radials from the board would be on a 20A, rare to run though due to the cost. Appeared that 6.0mm was cheaper than 4.0mm..

A 2.5mm radial is not expensive?? Or do you mean a 4mm? As has been said, no need to run a 20a radial in 4mm, and I'd like to know where you can get 6mm cheaper than 4mm!!

The reason the 1.5. is used for larger lighting circuits, is because the voltage drop requirements are more stringent on lighting circuits, and the longer length runs may cause performance issues with lighting circuits over a certain length.

In a domestic lighting circuit there is almost never any good reason for overspeccing and using 1.5mm^2 cable instead of 1mm^2. However, at least here, 1mm^2 is not readily available.

I worked for 2 firms who both insisted on using 1.5mm² for all lighting circuits. I still have no idea why.

I still keep a drum of 1.5mm² cable on my van but it's very rarely used.
 
I mean here as in Derry, and indeed the rest of Ireland.

Are we arguing semantics here.

FACT:
Derry (=Londonderry) is in Northern Ireland (part of the UK).
It is situated on the island of Ireland.

In your view, which part of that is incorrect?
 
The reason CEF in the south do not stock it is because it is not permitted by ET101 to use 1mm^2 cables.
If that's true (and I have no reason to doubt you), that obviously explains things! However, it introduces potential confusion for UK readers that would probably best be left to the "Electrics outside UK" forum!

Kind Regards, John

I didn't intend to confuse matters, but someone posted a link to CEF in the south and postulated that they must have been sold out of a cable because it was so "popular", completely ignoring the fact that it was in fact prohibited in the area where it was (not) being sold.

FACT 1: The legal name for the city is Londonderry, not Derry.

FACT 2: The country it is in is not Ireland.

FACT 3: The flag in Risteard's profile information is not the flag of the country in which he lives.

I'm quite prepared to accept that he wishes that none of those facts were true, but for now they are, and his information is riddled with errors.
 
I would think he probably means HEREProbably sold out because it's so popular.
No. I use CEF in the north rather than the south.
It was an attempt at humour as you seem to think you live there and CEF are rubbish.

The reason CEF in the south do not stock it is because it is not permitted by ET101 to use 1mm^2 cables.
Further proving my oft used "Never assume those in charge know what they are doing".
