It's dangerous to cut cables if you don't know which are the hot ones, since you run the risk of completing a circuit with the live wire, the scissors, your body, and the ground beneath you.
- somerandomqaguy 3y ago... wait, why would the chargers keep the the high voltage DC lines energized when not in use?
- gottorf 3y agoMy rough understanding is that AC conductors (energized, i.e. having a significant potential difference than ground) come into the charging stations, go through an inverter, after which point the DC conductors may or may not be energized. I don't think copper thieves would be able to tell accurately which wires are which. Mind you, I'm not an electrician or electrical engineer; I just work on my home wiring sometimes.
