Re: GFCI Breakers Help!

Inside these devices there is a sophisticated circuit to perform this function.
The circuit inside these devices is an active one and requires both the hot and neutral wires connected to the GFCI .... because it needs to directly sense the current between the supply and return .... the device needs the 2 lines attached to perform it's function.
The problem with the way you connected the wiring .... by only attaching the hot wire to the breaker and by having the circuit's neutral wire attached to the common neutral bus .... the GFCI breaker would be seeing a constant imbalance from all the other neutrals at the common bus and always remain tripped.
* IMPORTANT * .... for safety it's a good practice to shut off the MAIN breaker while working inside the panel.
By the way .... specialized breakers like this are the only time a neutral wire gets attached to a breaker.
So ... to answer your question ...
The GFCI breaker should have markings indicating which wire is attached to which terminal.
With the GFCI breaker in the OFF position .....
The hot wire feeding the circuit is attached to the connector that's identified as " Line Load " ( marked black )
The neutral wire for that circuit is attached to the " Load Neutral " ( marked white ).
The white coiled wire ( pig tail ) is attached to the neutral common bus.
Put the cover back on the panel ..... turn on the MAIN breaker .... then turn on the GFCI and test your circuits.
Hopefully this makes sense and helps.
Good luck and be careful.
