Is this an error

I'm a bnit bored and can't think of a proper question, so what about this one. On page 141 of GN8 (earthing and bonding), it has a nice picture of a bit of SWA. They are using the GREY core as the earth, sleeved green/yellow obviously. Now, I know it doesn't specify in the regs what should be used as what, but I thought it was an agreed convention that black should be used to avoid confusion with the old neutral colour, and that the NIC even brought out a guide to that effect. Have the IET got it wrong?

Only ever seen it once myself though! Wish wholesalers would stock it...

Bit to sensible and simple and might make things easier and safer ;-)

When I started it was Red = Live, Black = Nuetral and Earth was GREEN, then some young upstart changed it to Green and Yellow :-( Progress is just much too quick LOL

That's because single phase coloured SWA is generally 2 core, and 3 core is manufactured for 3 phase. It's hardly a pain to identify the conductors anyway if you wish to use 3 core for single phase is it ?

Nope it isn't ;-) But we like a good moan lol

If as a country we vote to leave the EU does this mean we can go back to RYB?....:smartass2:

Leaving CENELEC would be entirely more relevant to the issue.
