The physical size of the sensor window should be carefully determined by the physical size and conf iguration of the power conductors. The Ground Fault
Sensor will respond only to ground faults which occur between the position of the senor and the load.
*Dual trip current ranges 3.5 to 11 and 10 to 36.

electrical installations without the need for dismantling the primary bus or
cables.
CAUTION:
Proper safety precautions must be followed during installation by a trained
electrician. It is recommended that the incoming power de-energized before
installation. The sensor must have its secondary terminals short circuited or
the relay connected, before energizing the primary circuit .
