OPERATION TESTING
A. GROUND FAULT RESIDUAL METHOD - 3 Phase / 3 Wire
For circuit breakers with “G“, "V" or "W" in the catalog number. Reference page 2/10.
1. Set all trip unit settings to their maximum setting and on Model 586 trip units set GF TYPE = GND RESIDUAL.
2. The supplied neutral sensor wiring should be left with wires shorted together. Bundle the wires where convenient during the test.
3. Using Figure 1, connect a low voltage current source to the circuit breaker phase A.
4. Close the circuit breaker.
5. Apply a test current equal to 125 percent of the ground fault pickup setting for a maximum of 10 seconds.
6. Turn off the low voltage current source.
7. Verify that the circuit breaker tripped and then record the results. Proceed to step 8, if tripped, otherwise contact technical support:

www.usa.siemens.com/powerdistribution
8. Repeat steps 3– 7 for circuit breaker phases B and C.
9. Testing is completed. Turn off the low voltage current source and disconnect from circuit breaker.
For circuit breakers with “K“ in the catalog number. Reference page 2/10.
1. Set the GF ALARM SETTING to the minimum setting and GF TYPE = GND RESIDUAL. Set all other trip unit settings to their maximum setting.
2. The supplied neutral sensor wiring should be left with wires shorted together. Bundle the wires where convenient during the test.
3. Using Figure 1, connect a low voltage current source to the circuit breaker phase A.
4. Close the circuit breaker.
5. Apply a test current equal to 125 percent of the GF ALARM SETTING.
6. While the test current is on, verify the trip unit LCD screen shows GROUND FAULT ALARM.
7. Turn off the low voltage current source.
8. If GROUND FAULT ALARM was displayed, record the results and proceed to step 9, otherwise contact technical support.
9. Repeat steps 3– 8 for circuit breaker phases B and C.
10.Testing is completed. Turn off the low voltage current source and disconnect from circuit breaker.
