... I just know you'll love this one matey. A socket on its own, in a village hall. You tell me how this won't confuse the hell out of someone?!!

 

[Marvo]

It's confusing the hell out of me. So is each of those two sockets on different phases?

 

[Plonker 3]

Im taking it that there are pther sockets either side of that one on a different phase?

But as Marvo has said it does look like 415v sticker is i plying it in that socket alone.

Im taking it that there are pther sockets either side of that one on a different phase?

If it's referring to other sockets out of view on either side would you normally have to label like this according to UK regs? Seems a bit obvious to me that if the DB is 3-phase then there's probably going to be sockets on all 3 phases to achieve load balance, in my country the label wouldn't be necessary.

I think it was a requirement in the early versions of the 16th edition but no longer a requirement now.

I think you should have included Tony, we all know how much he loves stickers like this.

I'm fairly certain that it was not a requirement of the 16th ever.

From memory the requirement was for a label where a potential of greater than 240 may become simultaneously accessible to touch where not normally expected. Or words to that effect.

So 2 sockets near each other where you would need possibly 3 or 4 faults to occur to make the voltage simultaneously accessible didn't need labelling.

I knew this was stick up ..... by the heading

 

[Plonker 3]

As i said I think, i did my appreticeship from 1993 and remember working for a company who did a few industrial installs and used to put them up as obviously they knew the regs better than me at the time (or at least hope they did)

 

[Rockingit]

Well, if you wanted to simultaneously touch this socket and a neighboring one you'd need an arm-span of 7.5m!!

 

[davesparks]

I've got a couple of copies of the 16th somewhere, maybe I'll have a look sometime.

The thing with stickers is that it has become an obsession amongst even some of the most sensible people without any regard for common sense or the regulations.

 

[Andy78]

This is how it was explained to me..... The reg was put in to cater for instances where voltage was higher than normally to be expected, an example of american airbases on British soil was cited to me in this explanation, although I am sure there may be more instances in heavy industry of which I have no experience.

The reg was originally worded to state that labels were to be placed where voltage exceeded 240. This resulted in a raft of 415V stickers all over equipment up and down the land.

What was actually meant, and how the reg has now been reworded, was that voltages where Uo (nominal line to earth voltage) exceeds 230 should be labelled, as this is outside the normal expected range of supply.


Don't shoot me down for any poppycock contained within that lot..... it's second hand info at best.

 

[Plonker 3]

What you mean the regs have always been as clear as mud?

 

[Andy78]

[Marvo]

Well, if you wanted to simultaneously touch this socket and a neighboring one you'd need an arm-span of 7.5m!!

So the sticker is indicating that the two sockets in the picture are on different phases?
