This could be a daft, or really important question...

If you had a 3ph dist board and for example in the kitchen there was a dishwasher on 1 phase and the sockets on another, and their exposed conductive parts were within reach of each other must this be considered in case someone touches both in fault conditions and gets 400v up one arm and down the other or is it deemed such a small risk that you dont worry about it.

Like I said it may be a really stoopid question but I dont know the answer. Happy to look up in regs book but i think to find it (or not) it may take all night.

Thanks boys and girls

Very common on industrial lighting, where one or two phases are common in the grid switching.....BS answer is to clearly mark the switches or outlets, that 400v maybe present..

Not quite right, I got corrected on this a short while back and made myself sick on heaps of humble pie!

You only need to label when a nominal voltage higher than 230V to earth exists. Apparently the regs have changed and what you said was previously included, but now isn't

 

[old_sparky_RE]

From the BGB 514.10.1:Every item of equipment or enclosure within which a nominal voltage exceeding 230 volts to earth exists and where the presence of such a voltage would not normally be expected, shall be so arranged that before access is gained to a live part, a warning of the maximum voltage present is clearly visible.
230V to earth - no mention between phases. GN1 pg 25 also covers this.

So no labels required under 17th Edition

Tel are you saying you dont want pat testing stickers slapped all over your nice new 50 inch tv lol

 

[Eddiesparks]

Thanks everyone. I knew it sounded a bit crazy but I'm fairly inexperienced with the old three phase. Havent tested anything 3phase since college actually :-/

above the hot taps where i work they've put stickers telling you the water is hot

Was just gonna say that pepparz, I have seen hot water warning stickers on many publicly used taps before.

McDonald's put a heat warning on their apple pie thingies (can't recall the name) - when you bite into one you quickly discover that the contents is at about 500c :dizzy2:

 

[dazza1981]

On a hair dryer.....DO NOT USE IN SHOWER!!!!
Or maybe an electric fire....NOT DISH WASHER FRIENDLY
Or maybe our tool bags should be labelled....THIS PRODUCT MAY CONTAIN NUTS!!!!

 

[telectrix]

soon women will be coming home from the maternity wards with babies labelled...... DO NOT IRON: UNSUITABLE FOR MICROWAVE.

I sometimes wish they had put a sticker on the range on the counter in my local chippie

I always seem to have bare skin available for toasting when waiting for the chips, then leaning lazily until awoken with pain of biblical proportions



I had to edit the bare skin spelling,its just not me

 

[uksparks]

Are you saying then that now if you have two plug sockets say 6 inches apart on different phases, you would not put a sticker on between saying "<-- 400v Between -->" or is this a myth as I cannot seem to find it in the BGB.

A house that we have is being let out, its got storage heaters on a three phase supply in addition to the normal supply, i have put storage heater outlets literally 2 inches away from plug sockets on another phase. I have put a small sticker yet visible on the storage heater outlets that says ""<-- 400v Between -->" because I felt it right to do so encase some numpty doesn't realise if they get someone to look at it who's not me.

Don't get me wrong, I fully accept people might think whats that or get scared, but to cover my back I have put them on.

They should put a warning on all their food "Warning may contain lips, anuses, and eyelids, and taste like 3 week old warmed up roadkill"

A McDonalds not to far from here, actually it was my local one yet I never went in there, they used to sell a Spunk Burger, well one day they did anyway. Jist of the story is a lady had a burger from there, didnt eat it all and left some in the car, anyway, she then that weeks gets blisters etc in her mouth and on her lips. Anyway... jist of it is three different peoples jizz was found in the burger, and they all happened to work in the kitchen bit on that night she went in there.
