Ac Electrical System; Reverse Polarity; Connecting And Disconnecting Shore Power - Chris-Craft Lancer 20 Owner's Manual

AC Electrical System

The AC electrical system is an option and not available on all models. It is your responsibility to familiar-
ize yourself with the operation of the AC system.
The AC system operates on a standard 30 amp 120 volt, 60 hertz shore power system. Dockside power ser-
vice is available in 110 volt (North America) or 220 volt (European).
A receptacle at the stern of the boat allows for connection of the shore power cord. Shore power allows the
battery chargers to operate and charge the batteries. A circuit breaker protects the shore power circuit from
overload.

Reverse Polarity

Reverse polarity refers to the reversal of the ungrounded current carrying conductor and the grounded cur-
rent carrying conductor. The shore breaker automatically senses a reverse polarity shore power connection
and trips the breaker. Never
ing to shore power.
If a reverse polarity occurs:
1. Turn OFF the dock main shore power.
2. Verify the shore power cord is correctly seated and locked in place. Perform this step both on the vessel and at
the dock connection.
3. After verifying shore power cord is firmly seated, turn the dock main breaker back on.
4. If the reverse polarity situation still exist, disconnect the power cord and have the dock master check the wiring
at the shore power receptacle.
5. If the wiring at the shore power receptacle is correct, and a reverse polarity situation still exists, contact a quali-
fied marine technician.

Connecting and Disconnecting Shore Power

To minimize shock and fire hazards:
• Turn off the boat's shore connection switch before connecting or disconnecting
shore cable.
• Connect shore power cable at the boat first.
• If a reverse polarity warning indicator is activated, secure dock power and remove
power cable.
• Disconnect shore power cable at shore outlet first.
• Close shore power inlet cover tightly.
• Do not alter shore power cable connectors.
