Hello all,
Didn't get many responses to this but I want to pass some information on
regarding why 25 Amps was selected as the default test current. Apparently this
is a legacy value from the UK when 12 amp circuit breakers were being used as
mains breakers. A guess that 2 x 12 rounds up nicely
Hello Ron,
Yes, as you said. Burden was a poor choice of words.
In regards to your second query, as a matter of doing business, it is always
in a manufacturer's best interest to know what regulations apply to the use
of their products in the hands of their Customers. Having compliant product

I did a search on Hotbot to see what a Teslar is. Some interesting

There is a SASO standard for power outlets and plugs. However, I do mot have
the standard number readily available. But, I do know that the standard
references the UK BS 1363 plug and the US NEMA 5-15 plug. Also, to the best
of my knowledge, there are no mandatory Saudi approvals required for powe
Howdy all,
Having been involved with power cords and cord sets for quite some time I
have never seen an advantage in using "Universal" cordage. Therefore, I
would be interested to hear from people what they have to say about their
usage of "Universal" cordage and what they have benefited from usi

Hello Luiz,
Unless a specific standard specifies a length, there is no universal minimum
or maximum length. However, depending on the length, some standards specify
acceptable cross-sectional areas of the conductors for lengths below 2.0
meters (EN 60799) and above 15.2 meters (UL 817).

I recommend that you get copies of BS 1362 and all parts of BS 1363 from
BSI. You may also want to get a copy of EN 60799.

Power cord sets for the EU must be CE marked because of EN 60799, not EN
60950. Also, I know of one Austrian based power cord supplier that does
this. The IEC/EN 60320-1 connector has the CE marking molded on it.
As for a certification for EU compliant power cord sets, the supplier should

Hello all,
Earlier on in this thread it was eluded that this problem was leading to the
need of fused power plugs, similar to what is done in the UK. However, based
on the analyses of several people, I do not see how a fused plug would of

Hello Luiz,
When it comes to voltage ranges you are not going to get accurate
information from any source other than the power utilities in those
countries. However, depending on the power distribution network within a
country the voltage ranges can be different from one municipality to
another.
Hello all,
The reason why UL has split IEC 61010-1 into two standards (UL 3101-1 and
3111-1) has to do with the Instrument Society of America (ISA). The US
National Standard for Laboratory Equipment has been owned by UL while the US

You may want to take a look at IEC 61010-2-031 considering you are dealing

Howdy all,
I agree, there needs to be a curriculum available to teach product safety
basics at the University level. However, to truly look at product safety the
curriculum needs to focus on the application of engineering fundamentals to
the design and analysis of provably safe products, not a st
