Hi all, I would like your thoughts on this please... Ignore the retest date, should it have passed a PAT?
The lead is for a small SMPS, drawing 0.08A.
Thanks!

what does the lead have on the other end?

An appliance? or a "kettle plug" or other connector?

The other end of the lead has a figure of 8 connector that plugs into a SMPS
 
when I very briefly learned and did PAT, I recall that all extension leads/loose connectors had to be PAT, independently of any appliance they might have been plugged into. We used to have hundreds of them hung on hooks ready for use, so the question "should it have passed a PAT" is answered "it should have been PAT'ed"

I no longer remember the pass criteria for a lead. They had to have a visual damage inspection as prone to being dropped or trampled.
 
Fail for unsleeved pins (which make the plug over 30 years old)
... or much younger and "imported"! (although those 'imports' usually make the mistake of sleeving all three pins, rather than not sleeving any!).

I am surprised by this as in general regulations are not retrospective. Is it different for a PAT? Do things have to comply with the latest standard?
 
One of the principal reasons for failing a PAT is a fuse of too great a value. All plugs must now have sleeved pins; any which do not are non-compliant and may not be re-used. Looking at that plug, it looks like 0.75mm² flex, so a 5A fuse is indicated. The plug itself is highly unlikely to have been supplied with the cable, so has been fitted after original supply. This alone makes the plug non-compliant, so a fail.
 
We are told regulations are not retrospective so although we now have sleeved pins there is nothing to stop continuing to use the sleeved pins, the fig of 8 lead is rated 2.5 amp and so really should have a 2 amp fuse, however I would say that is being pedantic and 13 and 3 amp are the two preferred sizes so a 3 amp is ample.

However the lead is permitted in Europe and for rest of Europe there is no fuse in the plug so as long as fused under 16A is there really a need for a smaller fuse, the appliance needs to be 2.5 amp or less with a fig 8 lead, but does it really need to be fused at that? So risk assessment time, if something damages the lead could the fault be anything less than a short circuit? It would seem unlikely, and if a short circuit would a 13A fuse rupture? That seems likely, so in real terms a 13A fuse will protect the cable just as well as a 1A fuse, however this has to be down to the skilled person to decide.

With PAT testing we pay some one to use their skill to decide if the appliance is safe to use, they in turn take out insurance so if they make a mistake with their professional judgement the insurance will pay out, that is the whole idea of professional indemnity insurance, as the client all you need to do is check that insurance is in place. So end of the day it is the guy doing the inspection and testing of the in service electrical equipment who has to decide, the only point is where semi-skilled labour is used.

There was a court case not got links on this PC where a semi skilled guy sent to plug in a tester, when he got an unexpected result, likely OL and instead of writing that down he went into the rest hut and asked what the result should have been and wrote this down instead. The result was an error by both a plaster and plumber did not trip the power and a lady was killed as a result. However the point was it was not the semi skilled guy who was found guilty, but the foreman who was found guilty because he used labour which had not been trained to the level required.

This means the old idea of having a skilled guy do the first PAT test and selecting which code should be used on the tester and then using semi skilled to retest each year to same standard may not be accepted any more. Instead they pay the electrician by how many items he has tested and even when the quantity tested shows he has not really done the job they still accept the results.

I had a top of range Robin PAT tester, in the main only PAT testing was when we had repaired something and it was tested before being put back into service, however one odd day I was asked to do the PAT testing for a remote office and workshop, not too many items, so as an exercise decided to go for it and see how quick I could do it, I was really surprised, I averaged 1 item every 6 minutes, I had expected to be a lot faster, main problem was each time I moved to new desk or work bench the PAT tester did a auto self test, once the test button was pressed it went through the inbuilt test which took a fixed time, but these times are fixed in the IET guide lines when using an auto test, the manual testers are a lot faster, once reading steady write it down.

So semi skilled PAT testing is slower than skilled because it has to be automatic, there should be a window in the 13A plug where without removing a screw you can see the colour so know the size

spot the problem with that! So even with a window

you still need to open the plug to check size of fuse. So try timing your self checking fuse size, what we hope for is the PC and Monitor all daisy chained so earth wire onto monitor and one test but you stick labels on 4 items so although test took 8 minutes it works out a 2 minutes a test. But get a day where you find just 3 items a room and there is only one way to get your numbers up, stick on a label and run.

Question is what will happen if something goes wrong and it goes to court, it would seem likely from other court cases if the tester is doing 100 items per day or more, the court will find management at fault, it will claim management should know with that many items the tester could not be doing it correct. Yes where you sit in a workshop and all the items are brought to you 8 minutes an item is possible even faster, but you are suppose to test taking account of the environment, can't do that if sat in a workshop, however when I repaired an item it was then tested in the workshop so is that not the same.
 
There is no legal requirement for anything to be PAT.
There is also no legal directive to inspect and test fixed wiring either, however the Emma Shaw case shows what happens when the inspection and testing goes wrong. Section 7 of the Health and Safety at Work Act it seems has a far reaching power and if some thing goes wrong some one has to show they took reasonable steps to ensure the safety of others. The inspection and testing of in service electrical equipment (Proper name for PAT testing) is how we show the courts we took reasonable steps.

There is no legal requirement to stop you throwing slates off a house roof, but should you do that and hit some one with a slate you will still end up in court.
 
Wow, a wealth of information, thanks all!
So, fail for the fuse size (although if that size cable was <2metres and fixed,
with a moulded plug, would a 13A fuse be ok?)
As for the unsleeved pins, then if the lead is old is there no actual requirement to fail it as regs are not retrospective?

but it would make sense to change the plug. That lead is very old, and the plug may well have been fitted 30-odd years ago.

edit: added moulded plug
