power supplies and eliminates the need for a galvanic isolation system and a reverse polarity indicator. Refer
to the isolation transformer manual for additional information.
The main breakers in the AC Main Distribution Panel (AC MDP) are equipped with a selector slide to prevent
the shore power source and the generator source from being energized simultaneously and damaging the
electrical system components. These breakers protect the system and components from an overload. All AC
current is distributed to the AC components through individual 120V/240V (230V for CE) circuit breakers
located in the AC MDP.
TO REDUCE THE RISK OF ELECTRICAL SHOCK IN WET WEATHER, AVOID MAK-
ING CONTACT WITH THE SHORE CABLE OR MAKING A CONNECTION TO A LIVE
SHORE OUTLET. NEVER SPRAY WATER ON ELECTRICAL CABLES WHILE WASH-
ING DOWN DECKS.
TO REDUCE THE POSSIBILITY OF AN ELECTRICAL SHOCK, IT IS IMPORTANT
THAT THE AC GROUND SYSTEM IS FUNCTIONING PROPERLY AND THAT A
PROPER CONNECTION EXISTS BETWEEN THE SHORE POWER CORD, THE SHORE
POWER INLET, THE BOAT BONDING SYSTEM AND THE OUTLET GROUND CIR-
CUITS. IF THERE IS ANY DOUBT ABOUT THE INTEGRITY OF THE GROUND CIR-
CUIT, A QUALIFIED MARINE ELECTRICIAN SHOULD BE CONTACTED IMMEDI-
ATELY AND THE AC SHOULD BE DISCONNECTED UNTIL THE NECESSARY RE-
PAIRS ARE COMPLETED.
