ring v radial

[i=p/u]

thought never mention it but hey its actualy came to light that a ring can be double the length of 4mm radial..

if it goes out and back ( as a ring) then it will be double the length, as long as it takes the same route back. not if it returns via istanbul though.

Why go to all that bother............use 5 core ?

 

[telectrix]

Wired a three story house in four 32A 4mm radials as oppose to 32A rings, I really wished I hadn't, cost more, longer to run and had trouble with max Zs despite no faults found , had to knock it to 20A in the wbd

I've said it before and I'll say it again, 4mm would be much more useful if it had a bigger CPC.

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

whats wrong with swa as cpc ?
