Question: I have a luminaire that has a grey and black (three each) six-pole plug attached. Both halves are marked LEN.
The earth-marked connection in the grey half contains a wire that has a 240V AC or 16V DC control voltage for the fitting.
I am under the impression that no current carrying conductor can be in this terminal. Is it PURELY for earth or nothing? Can anyone tell me if this is the case?
Answer: From your description, this sounds to be a six-pole Weiland or Metway plug. It is usual for the black section to be the normal switched mains, and for the grey to be wired with an un-switched live and a control pair. My understanding is that each pin has an identical current carrying capacity and the markings on the grey plug are generic.
For a more complete answer you should contact the plug manufacture, whoever that is.
