Subject: Potentially DANGEROUS advice.
From: "Steve Lusardi"
Secondly, when plugging
in to shore power, never connect the safety earth line. Instead use a line
to your boat earth for the safety connection. Remember, your hull will
always be a better earth connection than the one from the distribution
transformer for the pier or yard and any leak anywhere in that distribution
net will use your hull as the preferred return path. This will create severe
electric corrosion on your boat and you will never know why.
I'd say Always make sure your green wire is connected to the shorepower, use an
isolator to prevent corrosion. If you need that green wire return due to a
short, the electricity will go back up the wire and trip a breaker. If its
grounded to the hull you create a very dangerous situation in the water around
the boat.
