Re: Line Filter

Hi, Jason

I am by no means an expert on 3 phase, but I have a little bit of
experience from work, and a little bit of coiling.

The L1, L2, and L3 should be connected to the 3 HOT wires.  The Gnd to your
AC ground.  I'm not completely certain what to do with N, but this should
be kept close to ground potential (it's neutral, not hot).  I suppose if
you're using a "Y", you could connect the N to the virtual ground created
by the "Y".  I reached the limits of my knowledge with that statement, so
I'll shut up.
