ELECTRICAL SYSTEMS
There are two separate electrical systems on board: 12 Volt DC and 120 AC. Both electrical
panels are located on the starboard side of the salon.
A.
DC SYSTEM (12 VOLT BATTERY)
This system powers most lights, and all pumps, electronics, anchor winch, engine starters and
the refrigerator/freezer.
1.
To charge all batteries you must activate the “Battery Charger” switch on the
AC panel, when connected to shore power or charging off the generator.
Batteries should be recharged daily. Either (a) run the engines for at least 3-4
hours; or (b) charge using shore power overnight; (c) run the generator for at
least 3-4 hours.
2.
The main battery selector switches are located in the engine room. These
consist of separate switches for the engines, house and generator batteries.
There is also a cross over switch that in the event of low engine battery allows
the engine and house battery to be tied together. The cross over switch should
always be in the OFF position when not needed.
B.
AC SYSTEMS (120 VOLTS)
There are two sources for AC power for this boat: (1) Shore power and (2) generator. Only
one of these sources can be used at one time.
1.
SHORE POWER: Dock shore power facilities come in three forms: 50AMP
service, 30 AMP service, and 20 AMP service. Most U.S. Marinas and docks
have 50 or 30 AMP service. Many, but not all, Canadian marinas and docks
have 20 AMP service. The “LATERISER” has 2 power cords for 30 amp
service (they may be connected end to end). There is a conversion cord for
connecting to a 20 AMP plug. When plugging into shore power you only
need to use the plug marked #1. This will energize all of the AC circuits.
With 30 AMP service, you will need to pick what power requirements you
want to use. With 20 AMP service, you will have to be careful what onboard
circuits you have on.
