International Power Cord Regulations How Are
They Applied?
When you undertake installation of your
devices with power cords, you must have
observed in the specification sheet that one part
of the cord is approved and another isnt. This
might lead you to wonder as to why is it so?
Well, it can be a bit tricky to understand
international approvals of cords. Lets
obtain a detailed understanding behind the
process of approvals and regulations.
? Approvals in parts Every power cord that
you come across is approved in its parts
and not as a whole. Its connector, wire
and plug are approved differently. Although
the IEC
2
standard connectors are used all over the world,
the standards of their approval change from one
country to another. This authorization depends on
the agency they are being approved by. For eg, in
China and Argentina, the whole cord set is
approved instead of its parts. ? IEC
Regulations The International
Electrotechnical Commission (IEC) based in
Geneva, is an association that establishes
international standards for the electronic,
electrical, and other similar technologies.
Before IEC standards are established, a consensus
is carried out wherein the experts
from different countries participate. As
mentioned above, the IEC connectors are used all
over the world and hence even if the approval
agencies are different, they must follow the
regulations laid by IEC (International
Electrotechnical Commission) ? Ratings based on
the current capacity The IEC 60799 5.2.2
states that The rated current of the plug shall
be not less than the rated current of the
connector. It means that the connector shouldnt
have a rating higher than the attached plug. Due
to this reason, the international power cords of
today have no approval on the IEC-320-C19 side of
the cord. For eg, The highest rating a UK plug
can have is 13A and if its C19 connector is rated
16A, IEC will not approve the connector as its
rating is high. The same applies to countries
like Denmark, Switzerland, Australia and
Argentina. The plugs available in these
countries have ratings lesser than their
connector. Looking into their specification
sheet, you will see that the power cords will
show NONE on the C19 column of approval. ?
Changing international standards Different
ratings are applicable on different chords in
different countries. IEC C13 power cords are
given approval by UL (Underwriters
Laboratory) upto 15A in North America. But
if you carry IEC C13 to Europe, it wont
be an approved standard because it is only
approved till 10A. Same holds true for IEC C19
power
3
cords. It is approved up to 20A in North
America and if you take it to other
countries, it wouldnt be considered an approved
standard.
  • The standards set by IEC (International
    Electrotechnical Commission) and UL
    (Underwriters Laboratories Inc.) differ notably.
    IEC standards state the minimum safety
    requirement for a device, whereas, UL
    specifies the technical details pertaining to
    application and product safety. We hope that this
    gives you a little understanding about the
    standards set for power cords. Keep reading this
