The most common positioning of the detector involves the horizontal and

vertical bus bar system and the breaker cubicle. If possible, supervise each

cubicle. Avoid placing the detector so that it sees normal light from the

breaker. See the example below about where to positioning the detectors.

The sensor can detect arcs within a three meter (118 inch) distance.
