Techniques for determining a potential electrical threat by a utility meter are described herein. A metrology unit of the meter is configured to receive electrical data associated with electrical usage at a location The meter is configured to determine, based on the electrical usage at the location and/or previous electrical data, abnormalities indicative of an unstable connection, such as a loose wire connecting a load to a power supply. The meter may employ a machine learned model or other algorithm to identify the loose wire or unstable connection and is configured to disconnect power to the location and/or send a message to an alarm device at the location and/or to a computing device remote from the location. In this way, the metrology unit can be used to mitigate potential electrical threats, such as fire, due to an unstable connection such as a loose connection.
