[AMPS] Question About Correct Phase for 240V Transformer Primary Windings ???

[Mark S Graalman]

  Hook the primary windings up in parallel,  if you
have the phase wrong there will be no voltage
output.  Might be a good idea for safety sake to
feed the primary with a low voltage transformer rather
than full line voltage.
