ELECTRICAL CONNECTIONS TO ALTERNATE POWER SOURCES
Figure 2: Installation for a 3-Phase 230 VAC Generator System
The boat’s generator does not have a 230 VAC output. How is 230 VAC power provided to the gyro
stabilizer?
If the generator does not have a 230 VAC output, it probably provides 115 VAC, 380 VAC, or 480 VAC.
If the generator output is 115 VAC, you have two possible options. In many cases, the generator will
actually have a 230 VAC output with a neutral connection. This allows 115 VAC loads to be
accommodated by wiring them from one of the 230 VAC lines to neutral
.
If the 115 VAC generator is
configured in this manner, you can provide 230 VAC power for the gyro stabilizer by wiring it line-line on
the 230 VAC output rather than wiring line-neutral. See Figure 3. Insure that a qualified electrician does
the wiring and follows the installation and wiring instructions provided by the generator manufacturer.

If the generator output is 115 VAC but is not configured to provide 230 VAC line-line, a transformer
will be required to step the voltage up from 115 VAC to 230 VAC. The transformer should have the
following ratings:
Primary: 115 VAC VA Rating: 3 kVA
Secondary: 230 VAC Type: Marine Grade, Auto or Isolation transformer
The transformer should be configured as shown in Figure 4. Insure that a qualified electrician does the
wiring and follows the installation and wiring instructions provided by the generator and transformer
manufacturer.
