3 phase conductor colours

Post by Energy »

Hi All,

Do three phase conductors need to be different colours or can they all just be the same ie red ?
doesn't seem to indicate that they cant all just be red in 3000...

Cheers

3.8.1; first para is bold typeface so is the fundamental requirement.
Conductor function must be identified: A, N, or E.
Doesn't say anything about distinguishing between conductors of same function.

So, assuming colour is the chosen means of function ID, then as per Table 3.4 an Active can be any colour except G, Y, G/Y, Bk, or lt Bl.
If colour is not the chosen means of ID, can be any colour except G, Y, or G/Y
