The plugs I refer to in being blue verses yellow were Cee Form of which I
stock lots of each type. This in addition to having lots of other Euro plugs in
stock some of which seem like they should have a
ground but have instead a metal plate with a hole in it and two round pins.
I also have had to deal with various colors of Speakon. The
NEMA code and
ANSI codes are simple and item specific sufficiently. The Lif code on the other
hand... given one can find a complete list for what means what and it's followed still, you will still find more than one lamp, much less more than one
base type at times called the same lamp coding. The Lif code is only one slight step above the J-Code used for Asian lamps.
The USMC at least used to only allow those with the higher test scores for aptitude into them. Much harder to get into them than the Army or Navy back than. This in the years right between those having the choice of joining the Marines or going to jail and no doubt these years now where in theory due to need for fresh meat, anyone somewhat breathing can get in to fill a recruitment requirement. Or at least in test scores that's what I heard at the time, we called them who were not so smart a rock. That is smart as one. I'm sure that today as yesterday is much the same but we did not need name tags.
In having or not having name tags, it was more what you could get away with in not having one verses having to have a name on your shirt. In getting yelled at or swiping gear, it was by far much better not to have your name plastered on your shirt. Otherwise in jest it was a question of not needing to have one's name so as to remember it. Such names on one's shirt took place as a change literally right after I got out.
Point is that just as Mayhem learned some about American wiring systems, and I learned Euro based systems, it's
par for the course that you and everyone else will also just have to get used to them. It's only going to become more common and I expect that our
stage pin plug is already becoming somewhat standard to find in Europe as with 120v
Edison in some hotels.
