A power distribution system for supplying AC power to loads includes an automatic wiring board that realigns voltages and determines a user-supplied wiring configuration. If an acceptable configuration is detected, an auto-wiring relay circuit closes relays to provide appropriate connections from a terminal block to power controllers that control delivery of AC power to loads, such as heating elements. If wiring configuration is incorrect or voltage is outside a safe voltage range, the auto-wiring relay circuit remains open to protect the controllers and loads. |
