This is the other
confusing thing that I forgot: There seem to be a lot
of different plugs for three phase used in the US. In Europe we have
the red five prong "CEE" plugs (actually IEC 60309 / DIN EN 60309) for
three phase. So there is allways neutral present at the socket. Though,
it is allowed to use a four leed cable (3P + PE) for equipment that
needs no neutral.
