Will a GFI circuit breaker be fully operational in a panelboard or load center which does not have a neutral?

Issue:
Proper wiring for GFI circuit breaker operation

Product Line:
Circuit Breakers

Environment:
Panelboards

Cause:
Operation of GFI breakers requires neutral connection.

Resolution: 
No.  The circuit breaker (GFI, CAFI, Dual Function) requires a neutral in the panelboard in order for the push to trip/test feature to operate.
In a sub-panel application, the sub panel must have a neutral which is not bonded to the enclosure.
