i am hooking up a G W M rotary phase converter, and i am having a problem
understanding the wiring diagram. it looks like you have to splice into(
1) 220 wire and connect it to L 1 in the convertor , and do the same with
the other wire and hook to L2 . then run a 3rd leg from T3 out to the machine
with the other 2 original wires . does this sound right


Yes -- other than lacking a visible means to start the motor
which serves as an idler. (There may be a way buried in there which
you can't see, which connects between one of the input lines and the
third line -- sometimes just a passive capacitance, and sometimes with a
voltage-sensing relay to disconnect start capacitors once it is up to
speed.)

Ideally -- there should also be capacitors to balance the
voltages and currents, but you can usually do without those, at the cost
of more (reactive) current -- it won't spin your power meter any faster,
but it might trip circuit breakers more often than you would like.

Good Luck,
DoN.
