Warning Labels inside consumer unit lid

[Ian1981]

Why don't we give the USA colour scheme a go, black for live (plus red and blue for TP) and white for neutral.
I'm thinking we could have a two year trial to see how everyone gets along with it

Yes they are way more advanced than us brits.
Let's ask the how they are getting on with AFDD's

 

[Dave OCD]

It does advise them to verify the function of each conductor though. They have then been warned to check this before working on it, so there is no real need for it to state what the colours mean (or, more accurately, what they should mean if the correct designations have been used).

Indeed, I often find 3 core SWA on single phase works where the black has been used as neutral and grey cpc. I think this was mainly soon after the changeover when confusion reigned [amongst some anyway ]

I think single phase should be red for line and magnolia for neutral as it is a neutral colour.

Its over 10 years since the colours changed........ anyone who is a competent spark, or has been through formal training in the last 10 years WILL know about the different colours installed in the past, and now being installed.

This is why the dual colour label is unnecessary

 

[westward10]

It has never been necessary.

How about someone who goes through formal training in 50 years time? Will they know the different colours used in the past?
How many people who go through formal training now would be surprised when they encounter the odd but of red white and blue which is still lingering?

Whilst agree that in a single phase installation there is minimal need for it, a three phase installation has a far greater potential for disaster from misidentified conductors.

and don't for get to put on danger 240 label on , they love them !

I wouldn't bother.
Regs requires a warning label when voltage to earth is above 230 volts only.

i can't help but feel that maybe if there were big unremovable labels on all sockets, accessories, etc. yes even making your pretty brushed steel screwless faceplate look ugly, then just maybe people might just have a little more respect for this electricity thing..

Makes no difference, as soon as an enclosure is opened the different colours are there to see. Whether it's now or 50 years hence, all the label does is inform that there are cables with different colour conductors, not what the colours relate to.

yes, but it works in conjunction with the clear marking at the interface between old and new colours as per 514.1.3 and the guidance of appendix 7. I think that the label serves no useful purpose at the moment, but years in the future it may serve a purpose.

label is extremely useful. can be used to cover up scratches where some ham-fisted apprentice has slipped with his Powerfix screwdriver.
