A 15 amp breaker will no more protect a 10 amp cord than a 20 will

protect a 15 amp cord

You cannot legislate intelligence





Intelligence? You realize a 15-ampere circuit breaker provides more

protection than a 20-ampere circuit breaker? You are aware of that ...

aren't you?



Where is your data to show that this is a real safety issue in the
real world? The folks that deal with safety and have the statistics
of the real safety hazards, ie NEC, UL are aware of the fact that
you can have 15 amp receptacles on a 20 amp circuit. The NEC
specifically allows it. As Bud suggested, if you disagree, take
it up with them. I suggest you have your data available that shows
this is in fact a real safety issue.

There a hundreds of millions of 15 amp receptacles out there and
there are plenty of 10 amp, 18 gauge ext cords available. Some
of those circuits have 15 amp breakers, some 20 amp. Should
be easy to show us the devesatation being caused. Statistics please.
And also the statistics are going to show a clear difference
between the fires, etc caused by those on a 20 vs 15, right?




As far as the ampacity of the conductors, it has nothing to do with the

problem ... as long as it's been evaluated as part of the "Listing"

effort.



Nonsense. As has been told to you a dozen times now, you can buy
a 10 amp extension cord and plug it into a 15 amp receptacle on
a 15 or 20 amp circuit. To say that the ampacity of the conductors
has nothing to do with it is ridiculous. There are lights in my
house that have 18 gauge cords, UL listed, no fuses in the lights
for additional protection. The ampacity of the cords is basically
the core of your safety issue. An 18 gauge, 10 amp extension cord
is not rated to support 15 amps or 20 amps. You could have a partial short
in one of those lights so that it draws 15 amps, exceeding the
rating of the cord conductors.



So ... you gonna do it like the NEC requires, or or you gonna ignore the

responsibilities imposed upon you by NEC?


Who is the "you" that is ignoring exactly what?
At least tens of millions of homes have been
built with 15 amp receptacles on 20 amp breakers, as allowed by
the NEC. They have been inspected. More of those will be installed,
inspected and pass electrical inspection this week.






Have a save 2014! I'm done trying to educate the "EXPERTS"(?).


As Bud said, take it up with the NEC folks and UL. They are the
experts that matter and apparently they don't agree with you or
this would not be permitted under the code. I'm sure they
will give it the attention it deserves.
