I see 25 of them. 25!!!

Most of which aren't in common use.
In residential use you only see Nema 5-15 and 5-20, with a 14-30
for the drier and 14-50 for the kitchen range.
The 5-15 and 5-20 are downward compatible

So you have 4 and we have 1. We win.

Hang on, you can connect a 15A device into a 20A receptacle, thereby having it fused incorrectly?

All of our 15a 120v equipment is listed to plug into 15 or 20 a
circuits. The only reason they have a separate 20a plug is for things
that draw more than 15a. They are actually pretty rare, virtually
everything has a 15a plug on it.

But you're plugging a 15A plug into a 20A socket, with 20A protection....

And what about all the 2pin and 3pin options? I thought you could have either, or is that France?

You can obviously plug a 2 pin plug into a 3 pin outlet.

Yet more complications.

The L versions are used in industrial and some commercial use.

All the rest are specialty and industrial. By specialty I mean things
like connecting travel trailers to power at travel parks etc.

If the sword man got out much he would understand once you get into
industrial locations there are lots of different plugs. Computer
equipment in Europe uses all the same plugs as we do these days. The
IEC 309 (big stuff) and IEC 13/14 (small stuff) has become pretty much
standard. Once you get away from the line cord, there are lots of
different plugs used on individual pieces of equipment. When IBM ships
overseas the only thing we change is the plug on wall end of the line
cord.

I wasn't talking about industry.
