[Amps] 240V Outlet

How would you know my view when I haven’t expressed it? I’ve only relayed code requirements. Our views are irrelevant. There are many different ways to perform a load calculation per the NEC, but using your feeling isn’t one of them. They are all well defined methods. You must use the full nameplate rating regardless of your opinion of how much it will ever draw.
 
You claim to know the limitation of my imagination regarding real world loads? Recording actual loads, analyzing graphs and numerical data, issuing reports, and making recommendation based on the real world data is a big part of my work. I am acutely aware of actual loads versus calculated loads in a wide variety of applications. How many load recordings have you evaluated?

You have a rather limited view of a world that far more varied than 
you imagine. I work in the world of pro audio, and there are many 
occasions where a product may be rated for 20A service but have very 
dynamic load requirements and draw FAR less current in real world 
applications. Audio power amplifiers are a good example -- a big 
power amp may draw 15-18A with both channels near clip on sine waves 
or very dense audio, but operating them under those conditions would 
be VERY rare outside of a test lab. Another example is a series mode 
surge suppression rated for 20A, with a 20A plug. There are MANY 
other examples that could be cited, none of which justfiy a 
dedicated circuit for a single product ONLY because it has a 20A 
plug.
