Concentrica cable

[sparkie-leeds]

Hi all,

As anyone used concentrica cable for a submain, apporx. 15-20 mtrs long

 

[nickblake]

how many cores does the concentric have is as Provided by the DNO alumin center surrounded by loads of neutrals

 

[sparkie-leeds]

i have not purchased it yet, looking at 25mm

For a sub main you’ll need split concentric cable where the earth and neutral are separated. You can’t use concentric. Split concentric it nice to use.

 

[sparkie-leeds]

So are we saying use split concentric

Yes you need split con but be aware you will probably have to give some consideration to mechanical protection as split con offers none!!

Let's hope you can make a good job of making off the ends, They can be a real pig of a job to make them look anything. The best way i know of, is to use a 3 spout heatshrink breakout, and heat shrink tubing for the Neutral and earth tails....
