So why do I hear all the horror stories about bad shorepower pedestals in Marina's etc.?
Is that a bunch of nonsense?
How can a neighbors boat be the problem, I've heard that for years, is it true?
On edit, if it can't be AC, then why do I have an isolation transformer isolating my boats ground on the AC side from shorepower?
I'm not doubting, but I am confused.
The problem in a marina if your boat doesn't have a galvanic isolator
, or ideally a isolation transformer is the AC ground (green wire) connects you to everybody else's bad wiring
scenario. It is DC, carried on the AC ground that is connected on most boats to the DC bus.
