Systems
As part of the AC boat circuitry the green ground wire
takes a diff erent path. It exits the yacht shore power in-
let or cord reel and travels to a galvanic isolator. See the
illustration.
A 60 amp (60 hertz) galvanic isolator for domestic use
is connected in series with the AC grounding “green”
wire. Overseas yachts
use a 30 amp (50 hertz)
galvanic isolator.
Th e purpose of the gal-
vanic isolator is to iso-
late the yacht’s ground-
ing system from the
shorepower ground. Th
e
galvanic 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. Th
is eliminates the possibility of galvanic interac-
tion from other boats in the vicinity.
Th
e green ground or “bonding wire” runs from the
yacht’s shore power inlet or optional cord reel to the
galvanic isolator. From the output of the galvanic isola-
tor 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.
Th
ere 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 yacht dealer for more information.
Do not to store objects inside the locker that might in-
hibit air fl ow to the galvanic isolator fan.
Normally the galvanic isolator is found in the lower aft
stateroom locker on the bulkhead (wall) near the for-
ward most bed.
