Hi Chris.

I was wondering about electrical on board the ISS. I'm an electrician so I was wondering do you have an astronaut that is an electrician as well or just highly trained? Do you guys have breaker panels or fuses?

What about the power generation, how often do you change the batteries? What happens if 1 panel in an array goes out?

Thanks, it's been awesome following you on twitter and reddit.
