Using Green/Yellow not as CPC

[Pete999]

Here's quick question...

Can I sleeve a green & yellow flex conductor with brown or blue to use it as a switched live or neutral?

I'm looking at a situation where I do not need the CPC connection (the timer switch I'm connecting to is class 2 insulated) but I do need live, neutral and switched live. So I'm wondering if I can use 3 core flex (so that the conductors are all insulated within the outer sheath, unlike T&E) and put a brown sleeve on the G/Y to use it as the switched live.

Thanks for your help, and sorry if this has been answered many times before!

No because the CPC is more than likely to have a smaller CSA than the other conductors in the multicore cable

I all, I am new in this forum and I subscribed because I found this interesting thread which is very much related to my inquiry. I have read all the posts and sorry I might not catch all the abbreviations.
I hope I make it short... I built a stepper motor cable assembly by using an off-the shelves cable which has four power cores colored blue, black, brown, and Yellow-Green. My motor is powered by maximum 48 V so is by definition ULV (Ultra Low Voltage) category in Australian Electrical Standards. So, as first, it is not belonging to the "dangerous voltage" classification which is highly regulated for use of Yellow/Green core, I have decided to sleeve my G/Y core on both ends with plain colour (Red was my choice but could be a different plain colour selected anyway). I need the for cores for my two phases stepper motor to work properly and the four cores have same section. Additionally both cable ends are terminated by connectors and encapsulated in backshels.
Does my decision sound lawfully correct ?
Thanks for replies and sorry if my post is not at the right place.

not sure of the regs down under, but as it's only 48V, think you can get away with it. after all, in the automotive field, all colours of the rainbow are used, even pink.

Tel, thanks it was early, just got up, taken my Meds etc, give a guy some latitude Mate.

latitude? is that a new kind of chic coffee, like latte, but with extra milk?

Doesn't most flex have all the cores the same size? If so the CPC will have the same CSA as the other conductors. If the appliance doesn't require an earth and its ELV then I can't see a problem.
