Off-topic (and I'm totally not expert, please please correct me if i'm woring) but the the real risk of a Carrington type of event is for the power grid, especially the destruction of equipment at end of power lines.

The idea is that those large transformer cannot be mass produced and could be completely destroyed.

The cool hack is that physical disconnection in time avoids those damages.

At small scale the difference of potential is not enough to fear much physical damage.
