Abstract

A wiring fault correction circuit for determining wiring conditions of an AC supply system includes: input line and neutral conductors connectable to the AC supply system; output line and neutral conductors connectable to a load; first, second, third, and fourth single pole, single throw relays; a first driver circuit for controlling 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 correctly wired AC supply system; and a second driver circuit for controlling 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 are reversed.
