When power lines are down or a circuit is opened for repair, lines between the generating facility and the open usually remain energized. You expect the lines between the open and end users to be de-energized, but that is not always the case. Unintentional re-energizing of power lines from sources on the consumer side of an open may cause electricity to backfeed – flow opposite to its usual direction. This poses serious risks to utility workers. If there is a transformer between the remote source and the open, backfeed through the transformer may cause normal transmission or distribution voltages to be present on lines you think are dead. It is crucial that you understand the causes of unintentional re-energizing and backfeed, and how to protect yourself from these hazards.
