Abstract

See full text

An open neutral protection method and apparatus including a blocking diode arrangement to prevent connection of power in circuits when the power source has an open neutral. In particular, when more than one branch circuits are connected to a power supply with more than one hot power lines, blocking diodes prevent back feed currents from activating relays connecting the power source to the branch circuits when the power source has an open neutral.
