SECTION 6 • ELECTRICAL SYSTEM
290 Sundancer
®
120 Volt / 60 Hz Wiring (Standard System)
The 120 volt wiring installed on Sea Ray
®
boats
consists of three (3) color-coded wires. The black
wire is the “hot” feed, white is the common, or neutral,
and the green wire is the ground. All branch breakers
and switches for AC equipment are installed on the
“hot” wire. The green conductor of the shore power
is connected through the galvanic isolator and then
connected to the AC grounding bus bar behind the
main distribution panel.
220 Volt / 50 Hz Wiring (Optional System)
The 220 volt / 50Hz wiring installed on Sea Ray
®
boats consists of three (3) color-coded wires. The
brown wire is the “hot” feed, light blue is the common,
or neutral, and the green wire is the ground. All
branch breakers and switches for AC equipment are
installed on the “hot” wire. The green conductor of
the shore power is connected through the galvanic
isolator and then connected to the AC grounding
bus bar behind the main distribution panel.
8. AC SYSTEM
NOTE: Actual usage of equipment will depend on the
amperage output of the power source available.
Line voltage from the shore power is shown by the
voltmeter on the main distribution panel. The main
breakers may trip if there is a surge in line voltage,
an electrical storm or an on board system overload.
The main breaker interrupts both the neutral and hot
feeds in the AC circuit to prevent equipment damage
due to internal overloads and external surges.
7. LIGHTING
Your boat is equipped with a variety of different
lighting fi xtures (See Fig. 6.9.1 and 6.10.1). Always
replace a bulb using the type and wattage of the
original bulb.
6. 12 VOLT ACCESSORY RECEPTACLE
Your boat has a 12 volt accessory receptacle on
the STBD side of the dash and one in the galley.
The receptacle is a cigarette lighter style plug that
may be used with any 12 volt accessories using
this type of plug.
12 VOLT ACCESSORY RECEPTACLE
(FIG. 6.8.1)
Never operate 120V shore power at less than 110 V.
