OPERATION NOTES
By grounding one leg of the isolation transformer on
the secondary side the "creation" of a neutral exists. The
"neutral" wire (blue) along with the 2 conductor (red &
brown) wires travel to a triple pole breaker located at the
output side of the transformer and eventually to the main
AC control panel. The green earth (bonding) ground is
connected as another continuing leg of the AC ground-
ing side of the circuit.
When energized the breaker passes AC current with a
transformer induced neutral wire to the ship's main AC
breakers.
Summary of Iso Boost Isolation Transformer-
A. The Iso Boost system increases the output voltage up
to 15% if the supplied voltage is too low.
B. The boat's electrical system and grounding conductor
are not actually connected to the shoreside system when
in use.
C.. Power is transferred from shore power to the boat's
electrical system by magnetic coupling. This means there
is no direct connection between the earth-grounded shore
AC power and boat AC power. The shore grounded con-
ductor is connected to a shield that is wound between the
primary (shore) and secondary (boat) transformer wind-
ings. This shield assures isolation on the boat by provid-
ing a protective layer between primary and secondary
windings within the transformer.
