I'm using the 'two phases + ground' configuration because I want my amp to also
work overseas where there is no 115v neutral-hot circuit available. Since no
current is supposed to flow in a ground, this means that even in the USA I can't
use any 115v components (relays, etc.) in my PS without a step-down
transformer.
I think that if I didn't care about the overseas issue, I would have brought out
both the neutral and ground to the amp so that I could safely use the neutral as
a return for 115v loads while connecting the chassis to the ground lead.
I don't like the 'neutral + phases only' configuration, because if the neutral
is used as a return and is connected to the chassis and opens, then the chassis
is hot. If the neutral is not used as a return, then this is equivalent to
configuration 1 above. If the neutral is not connected to the chassis, then
there's no automatic grounding when the amp is plugged in, and you have to have
a good external ground.
I'm not an electrician, this is just what I believe to be common sense! I'll be
interested to hear the 'expert' comments.
