A gold ring on her finger bridged the contacts and burned into her flesh until it melted enough for her to pull it off. Only took an jnstant. When the screaming died down and the pilot realized what had happened they went right to a hospital pad and were able to save her finger. I don't recall the breaker size but it failed to pop.
She was lucky. A colleague working on a car (not chopper related, I know) put his hand in the engine bay, wedding ring bridged between a 12V contact and engine block, in a few seconds it cauterized the blood supply; he lost the finger. Since hearing this I remove my wedding ring when doing work like this.
