Chapter 4

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.
