Trunking or seperate cpc???????

[Jay Sparks]

Hi Guy & Gals,

So, I was reading a very interesting thread earlier where the OP was asking whether to use SWA or singles in trunking/containment for a supply to a sub main.
The responses the OP got were different to say the least!!!!!!!

Anyway, some were saying SWA and some were saying singles with a seperate cpc and others were saying use the trunking as cpc.

Now Ive been on installs where the architect/designer has requested/insisted that a seperate cpc has to be used for every circuit. Ive also been in a factory, not so long ago, where the install was over 40/50 years old and the trunking was used as the cpc. Now this trunking was battered and some sections were rusty but I got a brilliant Zs at every point I tested.

So, I am happy to run a seperate cpc if Im told too and I am also happy to use the trunking/containment as the cpc (nice fence this.lol). Now obviousley cost has to come into it but what I want to know from you guys (without starting any arguments), is which method do you prefer and why???????

Here we go again. There was electricity BEFORE the 17th you know. We had the 14th when I started.

Absoblooming correct I bet some of our 14th edition installs are still going strong.

The way people talk about the 17th i start to think, "i must have killed thousands of people in the past"!!!!!!!!!!!!!!!!!!!!!

You forgot the flexible braids to the knives and forks.

"If it don't move, bond it!"
There were no arguments of is it extraneous.
