What size cpc is in 4mm? Is it 2.5mm?


Can't answer because the forum thinks the answer is too short

Whats wrong with 5th core as cpc in 3p/n swa?

whats wrong with swa as cpc ?

over a certain size its cheaper to run a single earth than using an extra core in swa (also means in a 90mm swa you wouldnt have to struggle to terminate a 90mm at the other end)

as for 4mm radials ived devided it up and none will be over 40m using 26A as Ib...

yes 5core swa it is but was thinking maybe cheaper to just run 16mm alongside maybe 10mm

for 25mm you dont need to do either.
use the swa for earth.

i know there is a max size but i dont recall exactly.

a mate way saying that you can use screen upto 25mm or so and above that you need a cpc but you can use both screen+cpc so its a smaller core

3p/N use 5 core.
Dedicated earth and Swa as belt and braces in case some idiot decides to guess at how to make an Swa gland off...........as Wade's post this week.

oops.............wade just posted the photo honest he didn't really make that end off) lol
sorry mate hahahaha
