Removing my chairman's cap for a
moment and expressing my personal opinions:
1) I am not intent on supporting outside wiring and I did
not see anyone at the meeting who was pushing it (I may have missed
though I was present 99.9%). As such I would say the PHYs of EFM
will not get consideration.
Works for me.
2) If anything that is being
suggested means my equipment can no longer push it as SELV, I am against
it. I do not believe that the voltages, amperages or wattages that
have been proposed push us beyond (or even close to) surpassing
SELV.
Again, works for me.
We need to add IEC 60950-1 to the list
3) No one can anticipate every
bad installation practice and correct for it in a specification.
Had the installer who tie wrapped the CAT5e cables to the steam pipe tied
them the to the furnace stove piping they would have combusted with or
without power. I would not say bury our heads in the sand; but, the
idiots often prove too resourceful to be thwarted at every turn.
We are in violent agreement.
