need of fused power plugs, similar to what is done in the UK. However, based

This subject of reliance on branch circuit protection for loads has been
discussed for a long time and involves a lot of historical tradition
and code and standards activities. The following is my understanding
based on some code committee activities, but I have not researched this

An in-plug fuse would not have helped in that case.

Gary,
I believe the answer is that the power cord rating of 6 or 10 amps is the
operating current, at which it will have minimum temperature rise.
