For voltage and phases you are correct as shown. Currents however will need toroid type current transformers installed so the motor lead is threaded through the toroid core. You get a voltage out that is proportional to the current in the motor lead. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
