Jonzjob Posted May 12, 2007 Author Share Posted May 12, 2007 Thank you for that Anton. This is an existing feed to a pool. Although I am a 'lekky it has been on aircraft and computers so I am not familiar with cable sizes. What would be the approx diameter of the 6mm cable. I do realise that the 6mm is the circumference and as I have spent the afternoon in the garden sun it's beyond me to think back that far and work it out [:D][8-)]!!! Ta!Edit : between better (and more intelegant) 'over 'arf we think that it should be 1.9mm, 2mm for cash? That looks about what is there...[:D] Link to comment Share on other sites More sharing options...
Gluestick Posted May 12, 2007 Share Posted May 12, 2007 JJ, just for you since you've been out in the sun!http://math.about.com/library/blcirclecalculator.htmA neat little online Pi calculator for all functions and expressions of Pi.BTW, the diameter for 6.m.m circumference would be 1.909859317102744 thus your 1.9 , or 2 for cash is very good since you are suffering incipient sunstroke!

Anton Redman Posted May 12, 2007 Share Posted May 12, 2007 The cable sizes are the cross sections of each of the individual copper cores. A 6 mm cable complete with three insulated strands and outer insulation is about the size of your little finger. Link to comment Share on other sites More sharing options...

I assumed, incorrectly it appears, that it was the cross-sectional AREA. ie 6 sq mm. If it's the cross sectional diameter then the cable would be pretty thick as each copper core would be quarter of an inch (in the old money!)Sid Link to comment Share on other sites More sharing options...

By 3 insulated strands do you mean line, neutral & earth and the outer size is as per petty pinky? Link to comment Share on other sites More sharing options...

Anton Redman Posted May 12, 2007 Share Posted May 12, 2007 To get 6 square millimetres you need a rectangle 2mm by 3 mm or about 2.5 mm diameter -- say 1/10 of an inch -- but you need three cores, insulation for each core plus an outer sheeth..Which takes you to as near as **** *** 10 to 12 mm.
