Ground-Fault Protection for Equipment
If circuit breaker does not have integral groundfault tripping or alarm,
skip this subsection.
A three-phase, four-wire circuit requires an external neutral current
transformer (CT). NOTE: The equipment
grounding connection must be upstream (line side) of the neutral CT and a
neutral connection must exist from the supply transformer to the equipment.
NOTE: Modified differential ground-fault circuitry and ground-source
return ground-fault circuitry require the use of a modified differential
ground-fault module (MDGF) and special current transformers. For wiring of
those systems, see the instructions with the MDGF.
NOTICE
HAZARD OF IMPROPER TRIP SYSTEM OPERATION
F1 and F2 must be isolated from ground.
Verify all wiring per the instructions in this bulletin.
Failure to follow these instructions can result in equipment damage.
- If load is connected to lower end of circuit breaker, connect load neutral to H1 terminal of neutral CT.
- If supply power is connected to lower end of circuit breaker, connect supply neutral to H1 terminal of neutral CT.
- Verify that F1 and F2 are isolated from ground.

-
Do not touch the terminals of the device during the test.
Failure to follow these instructions will result in death or serious injury.
Condition | Possible Causes | Solution |
---|---|---|
Circuit breaker fails to stay closed. | 1. Trip adjustment set too low. |
2. Undervoltage trip not energized.
3. Shunt trip energized.
4. Short circuit or overload on system.| 1. Adjust trip setting.
2. Energize undervoltage trip.
3. De-energize shunt trip.
4. Check system for short circuit or overload.
Circuit breaker trips, but no short circuit or overload is evident.| 1. Trip
adjustment set too low.
2. Voltage is below undervoltage trip setting.| 1. Adjust trip setting.
2. Check system for low voltage.
Push-to-trip button will not trip circuit breaker.| Circuit breaker already
tripped or off (0).| Move circuit breaker handle to reset, then to on (I).
Circuit breaker cannot be opened manually.| Damage to current path.| Contact
local field office.
