right! 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.

When I worked as a bench tech at a repair depot, guys were bad about
pranking each other. Our benches had a master switch which controlled
the power outlets on the bench. One hapless victim came in, sat down,
flipped the master switch and it was as though the sun suddenly appeared
for one second because some prankster had wired a bunch of 12 volt dial
lights across the 120 volt supply. I was always switching the contents
of freeze spray and tuner wash in the cans. I'd get an empty can for
each then using my handheld vacuum pump, pull as much of a vacuum as I
could on the empty can after which I simply plugged the small extension
tube between the spay nozzles and depressed them. Freeze spray into the
tuner wash can and tuner wash into the freeze spray can. When the victim
tried to spot cool a component, he got tuner wash all over his work. Of
course it evaporated in a few minutes. I wasn't so mean as to put water
in a can unless I was making a super squirt gun. ^_^
