Instructions for Field Testing of Ground Fault SystemsUtilizing agnum DS Circuit Breakers

The National Electrical Code makes the following state-ment regarding ground fault conformance testing:

NEC 230-95c

“The ground fault protection system shall be performancetested when first installed. The test shall be conducted inaccordance with approved instructions which shall beprovided with the equipment. A written record of this testshall be made and shall be available to the authorityhaving jurisdiction.”

This document is intended to provide instructions forconformance testing of ground fault systems utilizing typeMagnum DS circuit breakers. Although the most commonsystem variations are specifically illustrated, they are alsoused to form the basis for more complex systems. Theseinstructions may be applied, accordingly, on thesesystems as well. Refer to order-specific drawings todetermine the actual ground fault system supplied.

DO NOT ATTEMPT TO TEST THIS EQUIPMENTWHILE IT IS ENERGIZED. DEATH OR SEVEREPERSONAL INJURY COULD RESULT. TURN OFFALL POWER SUPPLYING THIS EQUIPMENT ANDCHECK FOR VOLTAGE BEFORE TESTING.

Overall system selectivity and performance of integralground fault protection equipment can be field tested onlyby using the high current primary injection method. Whentesting with this method, the following rules must befollowed:

1. Tests are to be conducted by qualified personnelonly.

2. The incoming line or source transformer must bedisconnected from the switchgear.

3. Loads must be disconnected from the switchgearwhen testing feeder breaker ground fault. If only themains or ties are to be tested, all feeder breakersmust be open.

4. A single phase high current power supply will berequired (approx. 1200A at approx. 2.5V). Flexiblejumper cables, equal to the current that will beapplied, will also be required.

6. On 4-wire systems, check to ensure that there are noadditional grounds on the feeder breaker neutralconductors.

Under a ground fault condition, the downstream breakerwill send a restraining signal to the upstream breaker.This signal tells the upstream breaker to begin timing(assuming the fault current is above their pickup settings).

TEST 1 – Self-Interlocked Feeders

Verify each feeder breaker trips with time delay whenself-interlocked.

Push test pushbutton and release to start the test. Thebreaker should trip with time delay. Push reset on Digitripand reclose breaker. Do this for each feeder breaker andverify delayed tripping occurs.

NOTE: Self-interlocking is defined as the feederbreaker having a jumper installed on secondarycontacts B8 and B9. When this jumper is installed, itallows the ground fault time delay to operate at thetrip unit setting. Without this jumper, the groundfault time delay will always revert to the minimumtime setting (0.1) regardless of the trip unit setting.The self-interlocked jumpers should only be on thefurthest downstream breakers in the zone interlockscheme.

TEST 2 – No Delay Trip On Upstream Breakers(Normally mains and ties)

Verify that each upstream breaker will trip with no timedelay (minimum setting 0.1), when not receiving arestraint signal from a downstream breaker.

Push test pushbutton and release to start the test. Thebreaker should trip without any time delay (minimumsetting 0.1). Push reset on Digitrip and reclose breaker,repeat test for each upstream breaker.

TEST 3 – Delayed Trip

Verify that restraint signal sent by a downstream breakerto an upstream breaker does cause a time delay trip.

For Digitrip RMS 520, use the Test Kits to initiate simulta-neous ground faults for both an up- and downstreambreaker. The upstream breaker should trip with a 0.5 secdelay. For all other Digitrip trip units, choose a feederadjacent to the main or tie that is to be tested. Push testpushbuttons on both breakers and release them simulta-neously. The upstream breaker should trip with a 0.5 secdelay.

The downstream breaker should then clear the fault. Ifthe downstream breaker fails to trip, the upstreambreaker will then time out and clear the fault condition.

If the fault condition is located between the upstreambreaker and the downstream breaker, the downstreambreaker will not sense the fault and no restraining signalwill be sent. The upstream breaker will then trip at itsminimum time band, regardless of the time setting.

The pickup and time delay settings on the main, tie, andfeeder breakers must be selectively coordinated.

Note: If individual breaker testing is performed withthe breaker withdrawn from the test or connectedpositions, terminals B8 & B9 must be jumpered toobtain time delay by use of secondary defeat adapter8779C02G05.

DIGITRIP RMSFIELD TESTING OF OPTIONAL ZONEINTERLOCKING

The following is a general procedure to check the zoneinterlocking functions and wiring. Primary injection is notrequired for this test. Drawout breakers must be in thetest or connected position. The breakers must not beenergized except control power. For RMS 520, use a TestKit for each trip unit to obtain control power. See Test Kitinstructions.

For all other Digitrip RMS trip units, use an AuxiliaryPower Module to power the trip units. The APM is pow-ered from a 120VAC receptacle, the power cord plugsinto a jack on the front of the trip unit. Auxiliary powermodule is required. The Digitrip RMS green status “LED”should be flashing.

Preliminary:

For ease of testing, make the following settings. Theyshould be turned back to the desired settings after testingis complete. Make these settings on both the downstreamand upstream trip units:

Test Amps = GFT

Ground Fault Pick-up = 0.35

Ground Fault Time = 0.5

Procedure is written for trip units which include an integral test feature. For trip units that do not have an integral test panel, use a Digitrip Test Kit foreach breaker to initiate a ground fault trip. Follow Test Kit instructions to initiate a trip.
