A 15A circuit breaker does not protect #16 or #18 wires. Include in your
petition to UL and the NEC prohibiting anything smaller than #14 wire.
My desk lamp deserves a #14 cord.
And include in your code change proposal correction for the blatant
over-sizing of protection for fixture wires in 240.5-B-2.
Also include in your code change proposal correction for the blatant
over-sizing of circuit breakers for motors, and even worse, welders. And
I don't even want to think about what they do with fire pumps - it could
cause a fire.
Everyone understands your argument.
As I have explained several times, including quoted above, 110.3
(inspection) is not used for "listed" equipment. The AHJ does not second
guess the listing standard. The AHJ determines the device is used
according to the manufacturers instructions and conditions of listing.
I am a licensed master electrician. I have explained how the NEC and UL
work.
Are you Pete C. in drag?


U.L. isn't the problem. They are doing it right!
The problem is interpretation of NEC. You can't protect a listed device
that utilizes a NEMA 5-15 power cord set from a 20 ampere circuit breaker.
Goggle McMaster Carr, extension cords. None are rated at more than
15-amperes @ 125 VAC. See the problem?
Funny, I have both 20 and 30 amp extention cords.

Funny on store bought cords and equipment, the plugs fail either due to bad
crimps, or the little wires breaking off a bit at a time. It usually starts
to get hot right at the end of the molded connector. The more the cord is
moved around, the worse it gets over time.
