The reg is 514.10.1 if anyone wants to look it up

The change is between the BRB and BGB ....... I don't have any copies of the BBB to look it up in there though.

The whole thing is nonsense if you ask me. It's a single phase outlet (well, unless wired very creatively) and the nominal single phase voltage in the UK is 230V. Mrs Jones does not need to be warned of a theoretical risk of ph>ph 415V as Mrs Jones has no business being anywhere near an environment and undertaking an activity where she might be at danger from it. Her husband, Mr Jones the Sparks, he understands about such things because he was trained properly and understands that you'd expect to find distributed and balanced phases around an installation.

FFS!!!

 

[Rockingit]

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

No, as it's just a double socket outlet. It's attempting to indicate that somewhere nearby there's another socket outlet on a different phase, but poor old Mrs Jones is just going to think that this is a very special socket indeed.

....but poor old Mrs Jones is just going to think that this is a very special socket indeed.

Poor old Marvo was also thinking it might be a special socket as well or at least it might have some hinkey wiring going on.

I've actually never seen this label anywhere!! Yet another totally pointless sticker, like the vast majority of all electrical stickers

 

[Baker1988]

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.

yes that is how i remember it, if the nominal voltage to earth is more than 230V then a warning label needs to be put in place but even 3phase does not exceed more than 230V to earth.

Unlike US-style duplex receptacles that have snap-out links and two sets of terminals, to the best of my knowledge there has never been a UK double, BS1363 or otherwise, that can have the two sockets split onto different circuits. Unless anyone knows of some obscure version that I've overlooked?

In the US it's not uncommon to run both hots to a duplex, break out the link and have 240V between the two 120V outlets. Did / does the NEC require any sort of labelling in this setup?

Well, someone bought a job lot for this place! Basically every socket outlet had one, irrespective of location, likely use etc.

...Right...i've got it...problem occurs at outlet,sparky separates each side and RFC becomes two radials,he checks his book,realises he'll have to change to two 20A mcbs,it's a 3ph board,applies sticker,photographs,posts on forum to get approval....:joker:

On seeing that picture I didn’t know whether to laugh or cry.

I’d have had to peal it off, it would drive me nuts every time I saw it!

If you mean using L1-L2 + E (240V) for each of the receptacles then it would be out of code as 240V has its own polarity pin configuration. Same goes if you brought L1 - L2 - N + E to the duplex and used one outlet at 240V and the other at 120V. They do however make a duplex outlet to cater for outputting both 240V and 120V....

On our plants that had dual voltages 433V and 550V the engraved switchgear or DB identifier would be blue on white for 433V, red on white for 550V. Unobtrusive but had the required information.

...Going off the sticker debate...The phrase above,Tony,was EXACTLY what an old boy i worked with,did utter,when he explained to me how to "some men" had a single ear-ring,in order to "signal" their differing sexuality :bow: ...he was a merchant-navy seaman for most of his early life,on STD's,he said "i've had all of em'",and,although his pipe got on me nads,he taught me all the knots and how to form a leaded monkeys' fist!...eee the things we did before X-box...

Somewhere back in the dinm and distant I once remember seeing a very old twin socket that had 2 seperate sets of terminals on the back,regarding the label I,ve seen them used in that situation before,however they were in a kitchen environment and the sockets were about a foot apart.The worst example of mixing phases was ironically in a training centre for electricians and other trades,I ended up working there as an instructor for a short period and one day was asked to remove 2 single metalclad sockets from below a 3 phase db,now out of the db was a 20mm coupler with a single socket on the end,out of the socket was another coupler attaching another single socket,removing the first socket revealed 4 wires 1 g/y earthing both,1 black looped for both neutrals,one red feeding first socket live and one yellow going through first socket box to live in second socket.Red went to a fuse on red phase and yellow to a fuse on yellow phase and not a sticker in sight 415 in the back of a single socket box!

No I meant (e.g.) a duplex NEMA 5-15, each outlet 120V but one fed from L1+N and the other L2+N. Apart from Phil's possible sighting I don't recall any UK outlet that can do this. Even the oddball multiples like the New Day 'Fireside' socket (1x 13A BS1363 and 2x 2A BS546 fused down in the socket) and the Wylex dual (1x 15A, 1x2A fused in the plug) only ever took one circuit.
