Split Core Current Sensor Model (NMI 1250-400)

The secondary side of these split core transformers is 110 milli-volts at 400 Amps.

You need to cap the black and white wires separately if the meter is not installed at the time the

current sensor is working.

Pull hard on the bottom section to open the yoke of the sensor. Install around conductor and

snap back together. Twist the black and white wires independently from each sensor. The

sensor wires and the voltage wires can be installed in the same conduit. You can run up to 2000’

with #16 gage wire.
