1. A test apparatus configured to test a motor starter, comprising:
a power supply configured to receive an applied input voltage and to provide an output voltage;
an output switch configured to operatively connect the power supply to the motor starter and to apply the output voltage to the motor starter when the output switch is actuated;
a test switch having an OFF setting and an ON setting, wherein a test of the motor starter is executed when the test switch is in the ON setting;
a test lamp configured to illuminate while the test is executed;
a time selector including a knob or switch configured to set a user-selected time setting from among a plurality of time settings, wherein a duration of the test is controlled by the user-selected time setting from among the plurality of time settings; and
a programmable logic controller (PLC) connected to the knob or switch of the time selector, and including code therein configured to receive the user-selected time setting from the knob or switch, and to apply a predetermined dip to reduce the applied input voltage to the power supply and having code therein configured to generate the output voltage applied to the motor starter for the selected duration of the test.
