As part of the AC boat circuitry he green ground wire
takes a different path. It exits the shore power inlet and
travels to a galvanic isolator.
A 60 amp (60 hertz) galvanic isolator for domestic use is
connected in series with the AC grounding “green” wire.
Overseas vessels use a 30 amp (50 hertz) galvanic isola-
tor.
The purpose of the gal-
vanic isolator is to iso-
late the boat’s grounding
system from the shore-
power ground. The gal-
vanic isolator allows AC
voltage to travel back to
the green ground wire at the marina power center in the
event a short exists on the boat. Also, the isolator blocks
any DC current from traveling on the green ground wire.
This eliminates the possibility of galvanic interaction
from other boats in the vicinity.
The green ground or “bonding wire” runs from the
yacht’s shore power inlet or optional cord reel to the gal-
vanic isolator. From the output of the galvanic isolator it
runs to the AC ground buss located behind the AC main
control panel in the salon.
Since the galvanic isolator is not polarized either termi-
nal can be used for the inlet or output side for the green
grounding wire. See the illustration.
There is a fan located inside the isolator. If you ever hear
the fan running the
isolator has failed
. Disconnect the
shore power from the boat and check the system. Call
your closest Regal dealer for more information.
Do not to store objects inside the locker that might in-
hibit air
fl
ow to the galvanic isolator fan.
