Abstract: An electrical instrument includes an input terminal block that allows customers to configure input power as either single-phase, three-phase delta, or three-phase wye, using shorting bars to connect appropriate line and/or neutral terminals to each other without the need for an external adaptor or converter, and without modifying the internal circuitry or programming of the instrument.
