The only twist lock , code wise, that i'm aware of is in 680, otherwise it's a matter of location, vibration, # of prongs....
The 'circuit that broke the panel's back' is much more interesting, seems like i'm always there myself, looking for non-coincidental loads,dead circuit runs, wondering if they can run it for 179 min's at a time,maybe a fancy T-switch,,,,etc.
I've been working on a large building (on a part time basis) where just about every panel is full. Every time some one added a light or receptacle, they just put it on its own circuit. That's fine, they rarely trip a breaker, but when I need a space, I have to do what Sparky does. Needless to say, there is no panel schedule to help me out.
Maybe I should'a been a piano player in a ...
Few things are harder to put up with than the annoyance of a good example.
One unused duplex receptacle that was a candidate for "cannibalizing" into the new circuit was split wired and wired with #10-3-G.
It was dedicated and freed up the two spaces I needed for one of the circuits. Two more recepts that were used occaisionally for Xmas lights, etc. were combined into one circuit.
A final unused recept near the first one was also canniballized.
Invoice? $111.74 and all future work sent my way... There will be lots looking at the mess they have.
I even told the owner, very seriously, not to let the fire insurance premiums get behind. Or rewire the whole leased building.
Tom... The music biz is worse... I was a "legit" musician before I was a sparky. Had to get a day job! Complete with college time at Berklee and WVU...Music Theory, Arranging and Composition major...no bull! I still make a little money in music, but I'll never recover what I've invested in time, schooling, and instuments/equipment...Even belonged to the AFM local in Morgantown once...
The spellchecker ain't workin'...

Hey Virgil, Another place for twistems is on cord connected showcases (NEC410-29). Sounds like your career change could be labeled as a humanitarian effort from the pics and tales you've got. (I played lead guitar in a band-late'60s to early'70s,made some $, but became a spark so I could eat every day)
