Current monitoring device
First Claim
1. A current monitoring device comprising:
- a current transformer configured to be removeably coupled to a power line within a load center and to generate a reference signal having a level related to a current level of the power line within the load center;
a sensor circuit connected to the current transformer and configured to convert the reference signal to a measurement signal;
a flexible cable having a first end and a second end, the first end coupled to the sensor circuit; and
a connection portion coupled to the second end of the flexible cable and configured to be removeably coupled to a communications bus within the load center;
wherein the sensor circuit is further configured to provide the measurement signal to the communication bus via the flexible cable and the connection portion, andwherein the connection portion includes a lid capable of being opened and closed and configured to clamp the communication bus in place within the connection portion when closed in a locked position.
