** Though it sounds frightening, the only likely result of the
conductors inside an AC power cable coming into contact is fuse
blowing, circuit breaker tripping or ELCB tripping.

After all, that is what they are there for....


I do agree ! The question that springs to mind, is what if the earth
conductor was OC or partially missing. There is/was the risk that
the whole saw could have become live.


** That is what ELCBs are for......


... Phil

Yes, You're right ! I was thinking along the lines of a home workshop
without mains/master ELCB protection device. Which I must confess, I
don't have. :-( Though I do have one on the extention cable that I
use outside for the mower.

Finally another fault I found recently. When cutting an IEC lead to
hard wire it into a terminal block inside a cabinet, found that there
was no earth wire for about 8" inside the cord, but just a hole next
to the other 2 wires where it should have been. IT could not have
been removed at any stage after manufacture, as the outer insulation
was intact with no cuts or other damage visible. Also it was missing
in the middle of the cable, not at an end.

A few months ago I cut off the end of an IEC cord to put spade lugs on it
for testing a 6031A power supply. Imagine my surprise when the inside
conductors were 26ga wire. The cords had a 10A 250V rating on it and a UL
stamp, likely forged.


I think it is a good idea to do the "electric jug test" on these
things. The cable will heat up
real quick in this case, and can be easily spotted as insufficient
cross sectional area of conductor.

Maybe its about time some bureaucrats thought about testing some of the
stuff they allow as imports, and actually reject some, rather than just
inspect the stamps and pseudo-ratings on the import forms. They are
quick enough to test local product, and make mfgs jump through all sorts
of hoops to get approval to make them. But I guess they dont want to
upset the countries they import from too much.

JW does not say where he got the IEC lead - maybe he imported it himself
( eg came packed with some item direct from China) and so he has only
himself to blame for not checking it out immediately.

A few years back, the topic was done to death on this NG and not a single
example was ever given of defective IEC leads being sold here in Australia.

Unfortunately, I'm not sure where it came from as there's dozens of power
cords all around here, but I'd bet the original source was from China as
well.

I have seen a few, all came with Items bought off Australian Ebay
sellers IIRC and 2 of them had US plugs

Try it on an electric jug, if you want some entertainment. Might make
a good you tube video also.


** Been there, done that with a dodgy IEC lead that came from in India with
a repair job.

At 11 amps, volumes of smoke poured and conductors poked out through the
plastic.

Not only was the gauge very light, but the conductors were some strange
alloy with several times the resistance of copper.

My report of the finding started am LOOOOONG debate here with Ross Herbert
taking up the cudgel ad the WA authorities getting in on the case.

I remember that from nearly 10 years back. Coments about "Miro the
