Replacing GFIC circuit breaker

[scout4bta]

The house was built in 1979.
Found that the bathrooms outlets were dead. GFIC Circuit breaker was tripped. Reset circuit breaker, hit the test button and it tripped the circuit breaker.
I guess that is good?
My only other option is to replace the GFIC circuit breaker.
The wiring from the old GFIC is different that the new one. How do I wire the new one? The coiled white wire I know goes the the neutral buss bar.
The other white wire is wired to a bundle of other white wires. I know that the black wire goes to the "copper" colored lug. Does the other white wire go to the other lug?

It looks like pieces of romex were spliced in the panel for gfci protection.

Wiring from the 70/80's usually put all baths, garage and exterior recpts on a single gfci.

Now may be a good time to easily split that into 2 circuits.

Just follow the wiring instructions with the new gfci cb.

I guess I missed why the old breaker is bad?

Also, is that the correct brand breaker for that panel?

It looks like someone has merged what were individual branch circuits on to a single GFCI breaker. Use one GFCI breaker for each of the individual branch circuits. as has been suggested. The GFCI must see equal current on hot and neutral on each individual branch circuit.

This GFCI circuit is the only one in the house which is the outlets in the 2 bathrooms.
I don't know if the GFCI breaker is bad but don't have any way to test it. I'd rather replace it.
The breakers are all GE.
This is how I wired it up. It's working. Let me know if it needs improvement.
thanks.

You need to pigtail the wires so there is only one of each under the lugs.

You have a way to test it, the test button. Turn it on and see if the outlets work. Push the test button and with it tripped, test the outlets to make sure they are off. Reset the breaker to verify they are back on, the end.

Edited to add: I've been shown it before, but don't have my own access to it, nor do I care to own one or look it up but according to the UL book, the only recognized way to test a GFCI is the test button.

As sparky says, those breakers aren't rated for 2 wires at each screw.

Pull them off, add a 3rd short piece and use the appropriate sized wire nut to hold them together. Then the single wire to the breaker.

The fact that there's 2 wires there makes me suspect it feeds a few circuits. I'm also betting your "false fault" on the last breaker was a legit trip, but you'll find out soon enough.

OK. I used the test button and it works. Plugged in a 750w elect heater, no problems.
I will pigtail the wires tomorrow.
