Right, Amprobes can only measure absolute current. Theorectically a

But that is pretty much impossible.

In case it might help, this is the design I used:
I have three rotary phase converters. The are all using a potential
relay for the start caps and a relay that pulls in the mains. So I don't
have to hold the push button and if the power drops out for a few
seconds the phase converter does not try and restart without the start
caps. I've not
Back when I put my 10 hp phase converter together, I found some charts
on the web someplace about suggested capacitor sizing. I found a cheap
supply of capacitors at Mendelson's in Dayton, Ohio
and bought a small box of them. I ended up using I believe, 4 - 330 uf

Gentlemen,
using a phase pusher capacitor is a cheap and common workaround when a
three phase supply isn't available. I have used this with a lathe for
some time, since a machine like this doesn't need its full power most of
the time and it always starts idling without load.

Hello Andy,
it's just the same here, if you separate the usual three phase supply
into three separate 230 V-systems, each defined to ground. I was talking
about a, say, small household, where only one of these phases is
available. Other households in the same building may have others of the
