Open neutral detector

A device for detecting an open neutral condition in a split phase power system for delivering power to an electrical distribution system, the device configured for being electrically coupled upstream of the device to a power source and downstream of the device to the electrical distribution system, and comprising:

• a plurality of power monitors comprising a first power monitor configured for monitoring a first current on a first powered line connected to the electrical distribution system, a second power monitor configured for monitoring a second current on a second powered line connected to the electrical distribution system and a third power monitor configured for monitoring a third current on a neutral line connected to the electrical distribution system;
• a controller in communication with the plurality of power monitors, the controller configured for:
• detecting when an open neutral condition is present in the electrical distribution system by determining, based at least in part on one or more of the first current, the second current, and the third current, instances when a power current is present on one or both of the first and second powered lines while a return current is not present on the neutral line, and
• causing an indication that the open neutral condition is present in the electrical distribution system in response to detecting the open neutral condition.
