A mate of mine has purchased an old 49 foot teak
vessel (Chinese Junk) and wants to turn it into a live aboard that they can also take out for Saturday and Sunday day trips around the islands here in Hong Kong
. The vessel is on a swing mooring
that will have power and water
run to it next week.
There are no AC circuits or shore power
connection currently, and only the 24 volt battery
bank for the single
208 CAT engine
. There is a small Honda generator
that has a car battery charger
to it for emergency
Today we had the new house bank batteries (two 12v 200Ah) we have connected in series for a 24 volt bank.
Before the end of the day we had installed a 32Amp (230v AC 50Hz) shore power
, a Shore/gen switch, a AC breaker panel. A Victron Centaur 24v 30Amp charger
As we sat and drank a beer
planning the tasks for tomorrow, we were thinking about the grounding.
The Shore Power will get the ground from the main cable coming from the shore service
, we are not sure where we should connect a ground wire from the small generator
that is there...
As a temporary fix, we would run the AC wire to the Shore/Gen switch so the AC breaker panel is the main path to the Victron 24v 30Amp Centaur Charger.
