Hi All,
I am a new owner of an old Kadey Krogen (1982 - 42'). I have been working with an electrician to upgrade/update electrical systems and have run into a controversy between the electrician and another shipwright helping install an vacuflush system. It has to do with whether the ac/dc negative buss is tied into the common bonding system of the boat. The electrician says that current North American standards say that they should all be linked. Others are saying that if you do this, and anyone accidentally miswires something on the boat, or a short occurs in a piece of equipment, then you can start to run currently through your thruhulls, etc.. leading to corrosion and loss (some even say you risk sinking your boat).
So- after a lot of reading I can see that there are very different opinions on this ... I wonder, for those with older boats, how did they do this originally in these boats? Any opinions or thoughts on the best way to go? I noticed that most of the thruhulls are connected to green wires that seem to be exiting from the original wiring harness (my boat has had a lot of 'changes' along the way) ... and currently it appears my bonding system is tied into my grounding buss (did some testing today with a silver chloride reference electrode).
Any thoughts?
Thanks
