Abstract:
1. A wiring fault correction circuit for determining wiring conditions of an AC supply system, comprising: input line and neutral conductors configured to be coupled to the AC supply system; output line and neutral conductors configured to be coupled to a load; first, second, third, and fourth single pole, single throw relays; a first driver that controls the first and second single pole, single throw relays to respectively connect the input line conductor to the output line conductor and the input neutral conductor to the output neutral conductor in response to a conectly wired AC supply system, wherein the first driver circuit comprises: a second driver circuit that controls the third and fourth single pole, single throw relays to respectively connect the input line conductor to the output neutral conductor and the input neutral conductor to the output line conductor in response to an incorrectly wired AC supply system in which line and neutral conductors of the AC supply system are reversed.
