Well, yes isolating the ground should greatly reduce such a risk. BTW contactors sometimes do stick.
4th question:

If so, you may be able to further mitigate accidental lurches the way Jerry does with that latching relay, though in your case, you'd may need to use a DPDT relay. Let me think about that. |
