Default AC wiring question - identifying neutral wire

That's dangerous in any case.

What are the other risks?


First off, I get the impression you
don't know what you're really dealing
with on that boat. I have the impression
from your posts that the wiring is not
properly identified and there is
incorrect wiring of neutral and ground.
These are not indications of a safe
electrical system and "ordinary"
prudence based on the assumption that
the boat is safely wired may not be
appropriate.

To answer your question, the main risk
is that any current in the ground wire
will cause a potential difference
between different ground points. Grab
two appliances with "grounded" cases,
one with each hand, with a potential
difference between their cases and the
risk will reveal itself to you. Do you
know that cannot happen to you on your boat?
