(B-1 is protection of the cord of a listed device) Also B-3

and extension cords with a 15A plug do not allow them on 20A circuits?
I see no reason to believe that is true (and it would be absurd).
Perhaps a cite? Try 110.2 (approved). "Listed" apparatus is normally
"approved" and 110.3-A (examination) would not normally be done. But
110.3-B (used in accordance with listing) is applicable. Fires are
likely from not using according to the instructions.


The regulatory inspection agency has the responsibility for 110.3B also
.. and they should understand and acknowledge that Listed equipment will
be interfaced with such branch circuity protection.

As I have already explained, "listed" devices will be "approved" by the
AHJ under 110.2.

110.3 (inspection) is irrelevant to listed devices -inspectors do not
"inspect" listed devices. They determine that the listed devices are
used according to the manufactures instructions and the conditions of
listing.

You either go all the
wall with NEC ... or accept fire and shock hazards as a daily part of
life. If done in strict accordance with NEC, fire and shock hazards
should not exist. This just isn't happening in the real world!

The system is working as intended by the NEC and UL.

Anyone can submit a code change proposal.

And anyone can petition the UL to change their standards.

I am sure your proposals will be appropriately considered.
