Don't understand the question.

I had not heard this ... I look in BYB section 312.2.1 fig 3.9 where TNCS and PME seem to be the same thing (?).Not all TNCS supplies are PME but all PME supplies are TNCS so how do you know if it's PME, will the DNO always put a sticker on?
Quite simple.I see now, don't see relevance of question though.
