Phil has quite a bit of electrical knowledge

Pity not as much as he thinks.

He is just extremely annoying.

In the running for understatement of the year!

At last count, Phil claims that fake IEC power leads do not even exist.
Regardless of the fact that I've initially offered one for him to test.
(No response yet as to his interest on this).

Feel free to use Google groups to gather evidence of your own.

** I was the FIRST person to raise the matter of fake IEC leads here on
August 2, 2002 under the heading " IEC lead scam ?? "

Hi to all,

I have in my workshop a standard (black) IEC female to three pin lead
which arrived with a repair job. The 3 pin plug was damaged so I cut it off
and began to prepare the wires when I stopped dead.


On the IEC plug is printed "10 A / 250 V " and on the cable itself is
printed "18 AWG x 3C " - it is 6.5 mm in diameter.


The wire in fact consists of 18 strands of 0.11mm copper or about 0.17 sq
mm in total while 18 AWG is equal to 0.82 sq mm.


The very thin cable actually used equates to a rating of maybe 4 amps -
this is very dangerous.


I will try to discover where this lead came from.


Regards, Phil

** No point in testing any lead when JT will not reveal where it came from.

No, but I buy a lot of stuff from China.


** Then the whole business of safety and compliance with standards is
YOUR PROBLEM - pal !!!

Cos YOU are the IMPORTER !!!!
---------------------------------------

The legal obligation of the importer ends at making *reasonable* ..


** Fraid you are completely, 1000 % WRONG !!!!!!!

Appliance leads ( IEC, extension etc) are PRESCRIBED items under
Australian electrical safety laws.

You cannot LEGALLY import and sell them unless YOU have obtained the
appropriate certifications and have the required labelling printed or
embossed ON the items - or you can be prosecuted.

Seems you have not got the faintest clue what all this is even means.

Go have a GOOD look at an Australian supplied IEC lead sometime - pal.

There have labelling codes on them that identifies the IMPORTER - and
that
is NOT on a foreign market one.

See all those funny 3 and 4 digit N, Q and V prefix numbers on the plugs
and
the cable ?????

Got any idea what they mean ????

Obviously not.

THIS FACT is where your smug arrogance is letting you down.

I really am not being smug in the least.


** You are nothing but smug.

You imagine you understand something you do NOT.

You refuse to be corrected.

That is smug.

But rather to get your ATTENTION and make you realise that you have NOT
done your homework re what has long been the LAW relating to importing
electrical / electronic items into Australia for resale.

A few minutes on Google turned up the page listed below from Australian
state bodies that regulate the sale of electrical goods.

They all say the same thing - the sale of imported appliances appearing on
the " Prescribed Items " ( aka Declared Items) list is * ILLEGAL * without
the importer first obtaining the required approval certificate from the
relevant state body.

Detachable AC power leads that come with practically every item of mains
powered electronics these days ARE prescribed items - the whole lot of
them. In the regulations, they are generally called " Supply Flexible
Cords".

Standard practice to avoid the absurd hassle of getting each and every AC
cord approved yourself - is to DITCH and destroy any non-Australian
approved AC supply cord that arrives packed with imported items and replace
it with one from a * known supplier* that has the required approvals and
markings applied already.

Eg; the Q1803 single channel CRO I bought from DSE a while back came
packed with an approved 1.8M long IEC lead - made in China but approved by
the Queensland authority.

The IEC female carries no: Q03584
The 3-core cable carries no: Q03403
The Aussie plug carries no: Q03586

The cable is further labelled as " 3 x 0.75 sq mm " and checks out OK on
that with 45 milliohms resistance per conductor.

A similar IEC that cord came packed with my Rigol CRO (direct from China)
has no such markings and it not legal to sell here despite it checking out
OK.

** Hi to all my friends,

following on from the "Appliance lead" thread  -  I was motivated to test a
length of nominal 10 amp extension lead, the kind you buy at a K-Mart store
or similar and marked as using 3 x 1.0 sq mm conductors with a 75C temp
rating.

I used a 300VA toroidal tranny modified with a heavy gauge overwind that
produces 3 volts rms at 30 amp continuous to drive current into a 1.1 metre
length of the above cable, with the blue and brown conductors linked at one
end. A Variac allowed the current to be adjusted from zero upwards to about
50 amps (short term only).

Finally I tied the head of a K type thermocouple lead tightly onto the
outside of the above cable it's mid point.

With the 1.1 metre length of cable lying on the bench, I increased the AC
current in steps until the thermocouple meter read 75C  -   it took half an
hour or so to finally stabilise.

How many amps did it take to reach 75C ??

Take a guess.

Today I was working with a colleague doing a network cable
installation in a local club.
While there, I noticed an black coloured extension cable of
approximately 15 metre, with moulded ends (ie: not home made) that
was clearly marked 0.75 mm sq on the cable.

If not for recent discussions on this forum, I wouldn't have even paid
attention to it.

It stood out because the writing on the black cable was in white. It
was connected to an urn. I would guess this would easily be a 10a
load.
The urn wasn't on so I don't know how hot it would get. I informed the
person in charge that the cord was illegal and should be destroyed and
replaced.
He claims that they bought a quantity of extension cords of various
lengths along with "disco" type lighting (spotlights, lasers, chasers
etc) from a "reputable (and PA) equipment supplier on the Gold Coast
and there was nothing wrong with the cord, it worked fine".
There were heaps of them used in their "nightclub" area for all the
disco lights, and also for plasma screens etc.

They couldn't get them anywhere else in black colour and "other
colours glow under the UV disco lights".
Told him that by all means keep them, if you want to risk a fire, and
to be responsible for the consequences.

** Where did you get that idea from ???

The 1 sq mm conductor, 10 amp rated extension cable I tested reached its max
safe operating temp of 75C with 24 amps passing through it.

A simple calculation shows that a 0.75 sq mm version would dissipate the
same heat per metre if the current were 21 amps. ( 21 squared / 24 squared
= 0.76 )

So there is a big safety margin above nominal for both cables and the
difference in current handling is fairly small.

Most IEC leads use 0.75 sq mm and so do many extension leads.
