Steve, you have to be careful cherry picking a phrase out of an article without reading all of it.
The first line of 210.52 says
This section provides requirements for 125-volt, 15- and 20-ampere receptacle outlets.
It does not apply to 240v outlets so they would be "other".
Alan, I hear you on the fuses but these days, if it exists in the world, you can buy it on the internet. I needed some real long stainless 12mm bolts for an outboard motor several years ago and they were unobtainium in the US but I found a German hardware company on the net that had them here in a week. Compared to the cost of most boat parts, it wasn't even that expensive
In real life we are not using 30a rings so if you just cut the 1363 off and put a 6-15 on it you should be OK. (15a O/C device on the circuit in the panel)
