Spot the error in this, then.

I received this yesterday as wiring instructions - spot the reason why I've just gone ballastic at them!

Use of the CPC maybe!

This is also the same bunch of muppets whose Polish installers kept managing to trip out a 4kW site supply by using domestic fan convectors to force dry their cement with.

They actually expect me to commission this for them. Er, hello?

 

[kenny7askew]

is it they are using green cpc for L2?

Spot on Kenny. Now then, for the bonus points, what are the two most relevant regs?

 

[kenny7askew]

1 think 514.4.2 for one i will have to think about the other

Having seen what they've left me with on site to commission (not quite like drawing), I can quite happily believe this is how their installers actually do it. And yes, I am toying with reporting them to Trading Standards.

I am not for a moment saying its not crap to do this,but what is important is whether its permitted or no

The regulation, as far as I can see, prevents the use of a single core cable coloured green/yellow along its length from being used
It does not prevent the use of G/Y in a multicore cable from being sleeved at both ends as a live

Reg 514.4.2 para 2 "Single core cables that are colour marked green and yellow throughout their length shall ONLY be used as a protective conductor and shall not be overmarked at their terminations, except as permitted by 514.4.3" (which is about PEN conductors)

Table 51 for multicore cables lists G/Y as a protective conductor.

What about them using grey to indicate neutral and blue for a live as well

There you go go rock,I have changed the bold in the quote to emphasise and repeat my answer

let's face it, the whole thing is a mess. They sell these sunken cellars for around £25k a time, look nice, poncy client is happy. Electrically unsafe, no 'emergency trapped' button inside if the door shuts, no guard rails around a gaping hole and installed by Poles that force dry their mix. But shiny shiny = ker-ching ker-ching. Stinks.

Sorry mate, you've lost me. There are only two types of cables - single and multi, and 514 talks about both of them, and on all counts says that G/Y shall only be used as a protective conductor and cannot be oversleeved at termination, even going so far as to specifying the colour ratio of G to Y and saying that the single colour green should never be used either. It even says that they shouldn't be alphanumerically numbered except for circuit ID purposes, so I'm not quite sure what you're driving at.
