I have, though about 10 years ago:
Metal = Class I - Bollocks
3 core cable = Class I- A strong indicator but not proof
Plug metal earth pin = Class I - Bollocks
Plastic case = Class II - No. eg Kettle.
Double box symbol = Class II - this is the only bit that is correct as
far as I can see.
OK - I know who not to use for PAT now....
Ring them up and ask them what might be a Class 0 appliance :)
Moreover, like most places you can omit the STD code when dialling
another subscriber within the same code from a fixed line. Within
Southampton you can optionally omit 023, not 0238 or 02380.
I am, just that while it may be against convention and annoy some, any
number starting 0238 is a Southampton number.
Their contact page has it in the correct notation, and I suspect the
webpage is made from some template that can't cope with the less usual
The 0207/0208 misconception came about because BT were running
out of numbers and split the original 01 code into 071 and
When the 020 code was introduced, many people thought that the
7 or 8 was part of the code because they had been used to this
differentiation for several years.
However, this has now spread to the new 3000 series of
exchange numbers, despite the fact that there never was an 031
Look on Google earth at virtually any London dhopping street
and you will find shops with the correct 020 code on their
frontage next door to a shop with an 0208 or 0207 number!
I ordered a spare part for something a few years ago from a
local supplier. I was asked for a contact number and said 8220
1234. "So that't 0208 8220 ..." came the reply!
Anything right would be more appropriate. Pat testing does not fulfil
a business's health and safety requirements, it no more grants
immunity from prosecution than a complete failiure to PAT anything
After that the website gets worse!
I would hope that whoever wrote the garbage has been separated from

Apparently now non-approved according to my source, on the basis that
a bulb failure would give a false negative. I always test mine at the
start of a job and (after using the neon screwdriver) touch the live
with a moving finger to be extra sure.
I would assume that was the case with any instrument, hence those
proving devices that seem to be popular now.
I watched a young electrician at my previous place of employment
unpack a Volage tester that had arrived from RS components and use it
to test the Voltage on the three phases of the smashed socket he was
to replace, the disconnection was carried out by a.n other.
As he grabbed his terminal driver, I stopped him and asked if he
thought it might be a good idea to test a known live first. At this
point he stuck the index finger in the handholding the terminal driver
out and wiped it across the most exposed phase.
I am not sure if this is an accepted means of checking phase Voltages,
but the technique would have been my ticket off many construction and

It would certainly not determine the voltage, but I suggest it must be
safer to find out under controlled conditions that a wire is live
rather than finding out later. I emphasise I would test with the neon
screwdriver first so the 'wipe' would be belt and braces. This is at
home where I decide the H&S rules!

We don't allow our students to go above 50V in my lab, personally I wouldn't trust most of them about 5V. Don;t forget the dangers of Neodymium magnets, put those in your pocket with some genital piercings for a laugh :-)
50V? God. Back in my schooldays, 11 year olds were experimenting with
CRTs, with 3500V or more on two banana plugs PLUGGED BACKWARDS onto the
protruding pins - ie: with the live pins sticking out each side.
Right next to them, the next child was doing an experiment with water!
