electrically operated fixed circuit breakers.
Ground-Fault Protection for Equipment
If circuit breaker does not have integral ground-fault 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.
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 a nuisance trip during closing.
