The History of IEC power cords
Do you know what is actually running this whole
world of internet, cinematics and computer
science? It is power cords! If you dont believe
this fact, just unplug your systems power cord.
You will see a good for nothing dark screen
because it is turned off. Power is still there
your tools and systems are there. Still, you
will not be able to use them and do anything
without power cords.

So, with that assertion, we can say that Power
Cords is one of the most crucially important
tools. It is supplying energies from generations
powering appliances for decades. Today there are
a lot of different categories of IEC power Cords,
which are technically advanced than its
predecessors. Power cords have seen drastic
changes in this long course of time. Constant
engineering and reengineering has made it more
technically advanced, power savvy and secure to
use. The latest and most modernized member of
this power cord clan is IEC320 power cord. It is
always interesting to go through the history of
a product and see how it evolved since its
inception. Today, we will go through the history
of power cords and will see, how time had
advanced it with new changes. Invention and
Early Development Systematic power distribution
setup was first developed by Thomas Edison in
1882. He used copper wire wrapped with jute
covered under Bituminous pipes. That was the
first power cord invented. With the occurrence
of time, new developments and improvisations
took place. In 1906, first armored cable with
properly vulcanized rubber was introduced, but
did it was too much expensive to afford.

Meanwhile and in later time as well, Aluminum
came into use but it proved to be failed
experiment. It was not safe because of
corrosions. The Revolution Time of Cords The
standard appliance connector became effective in
1920. In later years, appliance cords with earth
clips were developed. Usage of larger pins came
into the trend as they prevent arc formations
and provide break free connectivity. After
constant gradual development for more than five
decades, 1950 was the year of significant
development in cords. This time, 2-wire cords
were introduced, which were PVC insulated. This
invention became the ground of 3-wire PVC
insulated cords, which is the latest structure of
cords that we are using. Evolution of Protected
Power Cord In 1959, a German company introduced
first IEC power cord. They brought three flat
blade pins out of which, 2 were basic power pins
and the third one was earth pin. The traditional
metal caps, which used to be placed for earth
connection were no longer a part of the pin.
This innovation made cables safer

and well-protected to use. The pins were placed
in non-equilateral triangle form that gave it
set direction to plug into a socket. Introductio
n IEC Standards for IEC Power Cords With
extending use of appliances, which were operating
mostly on power cords, IEC 320 Standards were
introduced in 1970. IEC (International
Electrotechnical Commission) standardized and
defined specification for IEC 320 power cords.
New improvements were added in following years.
In 1994 with IEC 60320 standards, International
Electrotechnical Commission revised its
standards and defined 13 different connectors and
inlets. Todays Era of IEC320 power
cords Today we are witnessing the finest
generations of power cords. With the history
more than 1.5 centuries, power cords are
available with better standards, efficient
performance and utmost security. With constant
advancements in technology paralleled with day
by day increasing demands, power cords have
expanded its categories as well. There are
numerous types of cords are available in the
market out of which 13 are

standardized ones. Different cords are available
with different pinning methods and socket
compatibilities. These latest cables are
empowered to work on higher power capacities as
nicely as on lower power imputes. Whether you
want to run big servers or just want to connect
your phone with TV, IEC320 Power Cords can help
you all the way. So, this was a short and quick
recap to the journey of power cords. The
history of these itself shows that the end
product we are using today has gone through an
adhered human attention, which led it to such
gradual development.
