Hi all. Would a NEMA 16-30 inlet work for my Kal clone control panel in place of the 14-30 inlet receptacle?
Links would have helped a lot instead of forcing everyone to research just to answer your question.You already looked at both. Please give everyone a clue.Hi all. Would a NEMA 16-30 inlet work for my Kal clone control panel in place of the 14-30 inlet receptacle?
I'm an engineer and not a lawyer so I have trouble reading the code but I think 110.3(B) might be the gotcha. It says that listed equipment must be installed and used per instructions or listing. Presumably the NEMA specs/listing or whatever it is say that the 16 series are for 3ø and the 14 for 120/240. If you use them interchangeably is that a violation? If you are in a facility that uses both 3ø and biphase equipment you can see how doing so could lead to problems and that is why there are two types of plugs which have the same capabilities in terms of the number of poles and their current carrying capacities but which will not mate with one another.
Is there any technical reason you can't use either one? Will you ever accidentally plug in a 3ø solids pump? No on both counts. Is there a 'legal' reason you shouldn't use a 16? Perhaps.
But given that anyone who sells the 16-30 doubtless sells the 14-30 why not just get the 'right' one?
