Electric vehicle supply equipment includes a contactor having a first set of contacts and a second set of contacts, an amplifier circuit electrically connected to the load side output of the first set of contacts via a first connection and to the load side output of the second set of contacts via a second connection, the amplifier circuit being structured to amplify a voltage difference between a first voltage at the first connection and a second voltage at the second connection, and control electronics structured to compare the amplified voltage difference to a threshold voltage and to determine whether the first and second sets of contacts are closed based on the comparison between the amplified voltage difference and the threshold voltage.
