I am trying to solve a new puzzle but unsuccessfully.
This is a story about one panel mount connector, this is sold exclusively in China.
Part description: M6 binding post panel mount connector, 40A with banana.
The point is that this type of connector, it might be found over high current PSU (30~60V DC)
But this is also found over bench-top digital power meter (current terminals), which this will operate at 230V AC.
And in this application, electrical isolation requirements they are totally different, 500V RMS at least.
The one million dollars question: Which factory has the offering of the 500V RMS version, when no one in China has do anything about product certification.
1) No one of these products (M6 binding post panel mount 40A) comes as branded.
2) No one has laser printing, so to be available any product model identification.
With all these products looking identical, and with out factory made identification, no one is able to understand
which ones supporting high voltage specification.
