In NFPA 79-2007, Clause 13.5.9.2 states, "Electrical connections at motor terminal boxes shall be made with an identified method of connection. Twist-on wire connections shall not be used for this purpose."
What I think this means that wire nuts cannot be used in motor 'potheads'. Other than European (CE-Marked) motors, I've never seen anything other than wire nuts with or without electrical tape wrap for making these connections.
Which US motor manufacturers offer terminal strips or connecting studs in the pothead?
Alternately, what "identified" methods exist for this conection? I'm having difficulty finding suitable connectors that won't cost a fortune to implement, or that will fit three into a typical pothead.
Thank you.
I see that my question was modified for Political Correctness. I've never heard the term pothead for a motor connection box. Some interesting comments on this subject were found here:

Seems pothead is a Canadian term. I always thought that meant something else. Thanks.
