The interconnected system shall be evaluated to ensure compliance with the appropriate
schematic drawings. The proper location of sensors and power cabling shall be determined.
The grounding points of the system shall be verified to determine that ground paths do not
exist that would bypass the sensors. The use of high-voltage testers and resistance bridges
may be required. A simulated fault current is to be generated by a coil around the sensors.
The reaction of the circuit-interrupting device is to be observed for correct response. The
results of the test are to be recorded on the test form provided.
