[C320-list] Grounding and Bonding

[Warren Updike]

I've checked the wiring diagrams in my owner's manual, and they don't
indicate a cross-connect between the AC ground and DC negative busses.
Nigel Calder's book, "Boatowner's Mechanical and Electrical Manual," 3rd
edition, has very extensive coverage on the subject.  

This is most important for boats that sit in a slip connected to shore
power.  Even with AC power on the boat turned off, you can still be a victim
of galvanic corrosion or worse from neighboring boats.

It's not an easy subject to understand; but, there are years of experience
behind the ABYC recommendation to tie the AC ground to the DC negative.

Warren,
If I remember correctly, I do not think my were and I connected the two
negative buss bars behind the electrical panel.  Will check for sure next
time I am down to the boat.
