Bought a set recently from a Bedfordshire supplier, although a Chinese firm.
Couldn't believe the "mains" cable and the fitted fuse.
Mains cable is flat 3mm x 0.6mm. Fuse is 13A!!!
Plug is one of those Chinese specials with reduced dimensions.
See pic.

did you buy it like that? without the cover on the fuse?

I wonder if someone in the shop robbed the 3A fuse from it for something else

theres many products that come with 'low profile' moulded on plugs..... from reputable manufacturers... not just chinese cr*p.


"3mm x 0.6mm" doesnt sound right.... what does it say on the flex?

No I removed the cover to show the fuse, the cable is unmarked and the dimensions are as quoted, nowhere near a standard 6A flat cable. The worst part is that these are supplied with a 13A fuse fitted. Since posting I've removed the cover off of the control unit and the "mains" cable conductors are both white, the ends soldered onto the cct. board and secured with a blob of hotmelt glue (or similar).

Well, it appears to be C E marked. the fuse may not be relevant if the device is protected against over current by its internal circuitry.

It is certainly a low quality product in my opinion and I would throw it in the bin.
 
It doesnt need a 6A cable.... and TBH, a 3A fuse would probably be oversized for it anyway...
As mentioned, the internel circuitry will limit the load... but i dont think theres anything to worry about... as long as you dont plug it in with the cover off like that

I agree, it's entirely dangerous.
1. 13A fuse
2. Suspect cable.
3. No clamp on mains cable sheath.
4. Non-compliant plug body.
5. Sufficient isolation betwwen mains and led cabling?

I've had cause in the past to refer this type of thing to the standards body, they tried to fob me off and said go to Trading Standards. I had to read them their own regulations before they accepted the complaint.
Needless to say, I heard no more about it.
 
1. 13A or 3A…. It’s only there for short circuit, not overload.

2. Why is it suspect? It’s 2 core, sheathed and looks sufficient size for the load. If it doesn’t have a polarity marked, then it doesn’t matter.

3. The glue is holding it as it is, but the removed cover will grip the flex if replaced properly

4. Why is it non compliant? Other products use the same plug shape.

5. The set glue creates the isolation. The cable cannot move.
 
Agree with Littlespark,

Plus althought it's marked C E, that's not the E.U approval symbol, that's the China Export symbol.:eek:
On the true C E symbol both the C and E are formed from slightly more than half a circle.
In the above China Export symbol C and E are formed from half a circle.

However in almost all cases it's manufacturing companies that sign off the true CE approval and keep paperwork, the goods don't go to any independant lab for testing / checking so it's pointless relying on it being any safer with or without.

BS1363/A specifies the plug dimensions. If the plug doesn't meet these requirements I would think it is non-compliant.

My interpretation would be that the product has got a C E mark, not china export mark.
C E the left side of the E lines up with the theoretical tangent of the extended inner circle of the C

whereas the china export, the left side of the E lines up with the centre line of the C

BS 1363 plugs do not have a C E mark. The C E mark is a self certification that it meets relevant European standards the BS 1363 plug is for the UK market and must not be C E marked as National standards apply.
A C E mark on a BS 1363 plug regardless of type setting indicates = BIN. It is likely to be unsafe and should not be used.

From the picture (hard to tell) it also looks like the Earth Pin is sleeved which also indicates forgery and non-compliance with BS 1363 = Take it out of the Bin then throw it back in the BIN... but harder.

For reference see alsothe Code of Practice for In service inspection and testing of electrical equipment 5th edition section 10.14. for the correct markings that should be seen

The Uk Plugs and Socket (Safety) Regulations 1994 refer back to BS 1363 as required due to , for example, the use of circuits such as Socket ring circuits with 32 A / 30 A OCPD in the UK
 
The UK plug has the BS mark on it… not CE

The light control box has the CE mark. Stick a different plug on it, and it can be sold in Europe.

The plug is fine

The control box is fine (or was until the sealed cover was taken off)

There is nothing wrong with this being sold in the UK.
 
Looking at the picture on #3, I expect it was plastic clips that needed a screwdriver to prise open… maybe not secure now if bent.

Superglue would fix that
That is not always the case with these type of lights.

Also, is the output at mains voltage? If so, is the outgoing cable double insulated?

Cover secured with plastic clips, not bent nor damaged by removal. I am surprised anyone on here would consider a blob of glue to be an effective mains lead clamp. As said above, sleeved earth pin another pointer to non-standard plug, not that it goes anywhere-only a 2 core "cable". A fault leading to a fault current of a few amps would make for some pretty fireworks with a 13A fuse in the plug, also.
Will check it out thoroughly shortly.
 
Its a 2 core cable... .the earth pin of the plug isnt connected to anything... It could be a plastic pin.... it doesnt matter. Its there to open the shutters in the socket... nothing else.

Is there a double-insulated symbol on the controller anywhere? square within a square?
 
The plug is fine
I beg to differ. A BS 1363 plug can have a solid plastic pin for use as an Insulated shutter opening device (ISOD) on devices where such is suitable. They can of course be solid brass* however, this plug is marked BS1363/A and a BS1363 plug cannot have a partial sleeved earth pin so an Earth pin part sleeved is ALWAYS counterfeit.
The plug is counterfeit but marked BS 1363 why would it not be, it's counterfeit anything goes, so what makes anyone feel ok saying the rest of this device is fine to use if the plug is simply changed?
Put what ever marks you like on it. Put 'BS 1363' on a plug that is not BS1363 compliant, mark it with anything you wish, mark it as double insulated and if it should be marked such what does that now tell you?

Most will buy and not give it a moments thought, I have seen these plugs come apart leaving the pin from the line conductor live in the socket after the plug was 'removed'.
I have seen fake BS 1362 fuses, who knows what they will take under fault. On some the fuse is for show and the cables are connected direct to the pins. As I said anything goes.

What is the specification on the cables insulation?

I could go on. This item is not fine and should not be trusted but just my thoughts you have yours.

My view... Destroy it or hand it to Trading Standards.

The photograph of the plug does not show clearly that the earth pin is part sleeved at the angle taken.
I wonder why a counterfeiter would invent a new way of manufacturing a plug pin where they could just copy the right way…. And to make such an change that it is an obvious tell that it is counterfeit. Their sales would drop.

You are right in saying they can place whatever mark they like on it… BS numbers, double insulated symbol… or CE instead of C E?


Look… if you are worried about it, take it back to the supplier and get your money back…. Difficult now that it’s been taken apart..

Or, take it to trading standards with your concerns. Let us know how you get on.

Otherwise, plug it in, hang it up and have a merry Christmas.

As mentioned above, that plug does not meet regulations purely on the sleeved earth pin, which is a definite no-no.

I suspect the body dimensions are also not sufficient, but difficult to be sure.

Non compliant and shoddy. I wouldn't use it.

Correct, fuse is not in circuit although it is connected to live. I'm informing the supplier and telling them trading standards are being informed.
 
Good call Sir. Seeing it more and more and many less informed than yourself are risking lives and / or fire

It's also quite common that the 13A plug pin separation is incorrect, resulting in stress on the plug body which results eventually (as said) in pins being left in sockets.
Attached a horrific example of one I came across, too many things wrong to list..
(and it had a metal case with HV in too-close-for-comfort proximity inside.)
The problem is most non-tech people won't notice...
I didn't report it to T.S. There are hundreds of thousands of Chinese sellers selling dangerous items, I'm afraid the battle is already lost.
I think the answer has to be better education by T.S.

Seen similar myself. It's scary the amount of stuff out there that doesn't comply with standards.

It does not help with those work places that deem a 'PAT' test required employ people who simply do not look with any understanding at the items. The level of knowledge some have is abysmal.
Many times seen these issues on devices carrying a 'PAT' label. Does not inspire confidence.
 
A local “trader” some years back was selling computers with mains plugs similar to that posted by w0z above, that went to trading standards too. Meanwhile the current TS man has taken the lights and forwarded the info to TS local to the supplier. Full refund given, didn’t ask for the lights back either.
The TS guy had one of these from ESF for a quick check of the plug :

Very handy.
 
Here's an update for anyone interested:
Trader's address is actually a Chinese "fulfillment Centre" , All items arrive ready bagged from China and a delivery address is stuck on and in the post it goes. It seems that this is a nice way of circumventing checks in this country due to legislative weakness- aka "removing red tape". Trading syandards in Bedfordshire were able to identify the item from the Chinese QR code on the back of the package and they are now in discussions with the supplier. Meanwhile,I opened the plastic box with my thumbnail - ludicrously easy, to see what was inside - see photo. The 4 semi-circular plastic lugs holding the cover can be seen near the box corners.
Mains in was on A and C contacts with live on A - less than 4mm from + contact at one point.
Led strings connected to +, 1 and 3 conns. String common connected to contact 1
Isolation of control ic from mains provided by 2Megohm resistor and ic on the top left.
All in all a nasty piece of work.

As expected. Great job following this up.
No robust separation and all in all a fatality waiting to happen.
 
No and that is quite common on these counterfeit 1363 plugs. That is to have a fuse carrier yet it is not in-line with the load
Yes, I know, I was referring to the PCB, whilst a (very low current anti-surge) fuse might not cover all eventualities at least it might give some protection to avoiding the possibility of mains through the light string if there was an short or low resistance path through the PCB.
Anyway all that said the answer is to educate the public, but sadly price continues to trump safety.
I suppose on the plus side we have yo hope that most users with have RCD or othe CU's, but I still know people who don't, mainly elderly. Fortunately they are not likely to be buying Chinedse carp.
P.S.
I'm in the process of "improving" the plug template referred to above, (putting measurements on it and other changes); if I ever complete it I'll post back with a printable file (If it doesn't break any rules or laws)
