This conductor is attached in the breaker as opposed to the lug. It appears that the breaker was opened and conductor attached internally. Never seen this before. Yes, I called it out. Wondering if anyone has some insight.
You’re holding an abandoned GFCI breaker. The white “pigtail” comes that way from the manufacturer. There are some other abandoned conductors in the panel. I suspect there use to be a hot tub.
As Richard stated that is a 2-pole GFCI circuit breaker. The white conductor is the factory pigtail for the neutral connection to the neutral bus. Regarding the breaker there is nothing to call out being that it’s just a spare circuit breaker.
Do you always remove breakers from a panel while inspecting?
Are you an Electrician?
Because “calling it out” screams unknowing electrical knowledge, you may want to check here, on this forum, before reporting on something that you are not familiar with.
Just a thought.
Not to worry. Most have done it.
I reported on this split bus as odd early on:
Didn’t I already passive aggressively ask him that question?
No.
One… that’s a statement, not a question, and two… I see abandoned breakers in the bottom of the panel (not installed), and on top of the panel (exterior of the panel) all the time!
Photo shows the breaker was installed!
I said, “you’re holding…” as if to say “why are you holding?” or “why did you remove it?”. Classic passive aggression.

Photo shows the breaker was installed!
The last photo shows it removed…abandoned!
Thanks guys, much appreciated. It was one of those “ahh” moments when I realized the obvious… when you pointed it out.
