You can easily overload a listed 10 amp extension cord with
a NEMA 5-15 plug even on a 15 amp breaker - You seem to be
a very strong advocate for "nanny state" interference at
all levels of life - the government has to protect
everybody because they are too stupid to protect
themselves. It's bad enough that way in Canada already.
You can't legislate intelligence, and you can't outlaw
stupid. And getting the government involved in "protecting
the people" against everything just guarantees that
"stupid" wins. Are you a lawyer, or do you just play one on
TV?????



This is called an "Appeal to Authority" argument (Goggle
it!).

No, I'm not a lawyer. However, I am a Licensed Professional
Engineer. I've engineered "Listed" equipment, and designed
branch circuit protection for DOD facilities. I'm not aware
of any fires/shock hazards attributed to my works over the
past 45-years.. However, I've determined the cause of fires
of several facilities .... all due to improper branch circuit
protection, and yet the "As-Built" drawing, reviewed and
certified by the local regulatory agency as complying with
NEC, didn't comply!

If there we're accountability for improper branch circuit
protection, and the resulting fires and shock hazards, this
problem would be cleaned up. The forum has really exposed the
ignorance and arrogance of the user's of NEC ... and at all
levels.

I'm prepared to support my argument in court, as I've done
in the past! Would you?
A good friend of mine is working on an "intelligent " power
plug system that would read the power rating of the load and
program the protection level of the outlet to match - but it
cannot support an extention cord.

How does that work? Why not just fuse the plugs, as the Brits
do? Simple beats complicated all to hell.

I'm sure you know that a lot of gear has a fused IEC14 inlet on
the back of the case. If the equipment short circuits, the fuse
blows and I would guess prevent an over current on an undamaged
power cord. ^_^

Sure, but that doesn't protect the cord. It's obviously not a
sufficient problem to get the NFPA's interest.

I seem to recall reading something about New York City not allowing any
power strips whatsoever. Those ubiquitous surge arrester strips were not
to be used by anyone and I found it quite puzzling. If it's true and I'm
not just remembering things that aren't there, perhaps one of my Damn
Yankee cousins could set me straight. ^_^

When I was working for IBM, the normal commercial power strips were
forbidden. They had some "listed" ones that were used sparingly. The
strips mounted on benches were allowed, but pretty well controlled.
Extension cords were strictly forbidden for anything other than a
*temporary* installation. At my CPoE, I am allotted *one* duplex
outlet. That has to do for not only my four computers (laptops),
three monitors, and all of my lab equipment (scope, power supplies,
meters, etc.). I have power strips plugged into power strips, three
deep. Everyone is in the same situation and some have even more
equipment in their cubes.
